The problem is inspired by the proliferation of large-scale distributed file systems supporting parallel access to multiple storage devices. Our work focuses on the current Internet standard for such file systems, i.e., parallel Network File System (pNFS), which makes use of Kerberos to establish parallel session keys between clients and storage devices. Our review of the existing Kerberos-based protocol shows that it has a number of limitations: (i) a metadata server facilitating key exchange between the clients and the storage devices has heavy workload that restricts the scalability of the protocol; (ii) the protocol does not provide forward secrecy; (iii) the metadata server generates itself all the session keys that are used between the clients and storage devices, and this inherently leads to key escrow. In this paper, we propose a variety of authenticated key exchange protocols that are designed to address the above issues. We show that our protocols are capable of reducing up to approximately 54% of the workload of the metadata server and concurrently supporting forward secrecy and escrow-freeness. All this requires only a small fraction of increased computation overhead at the client.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Geocast refers to the delivery of information to a group of destinations in a network identified by their geographical locations. It is a specialized form of multicast addressing used by some routing protocols for mobile ad hoc networks. A geographic destination address is expressed in three ways: point, circle (with center point and radius), and polygon (a list of points, e.g., P(1), P(2), …, P(n–1), P(n), P(1)). A geographic router (Geo Router) calculates its service area (geographic area it serves) as the union of the geographic areas covered by the networks attached to it. This service area is approximated by a single closed polygon. Geo Routers exchange service area polygons to build routing tables. The routers are organized in a hierarchy. Geographic addressing and routing has many potential applications in geographic messaging, geographic advertising, delivery of geographically restricted services, and presence discovery of a service or mobile network participant in a limited geographic area (see Navas, Imieliński, 'GeoCast - Geographic Addressing and Routing'.)

Most of the works on network coding-based opportunistic routing in the literature assume that the links are independent. This assumption has been invalidated by the recent empirical studies that showed that the correlation among the links can be arbitrary. In this work, we show that the performance of network coding-based opportunistic routing is greatly impacted by the correlation among the links. We formulate the problem of maximizing the throughput while achieving fairness under arbitrary channel conditions, and we identify the structure of its optimal solution. As is typical in the literature, the optimal solution requires a large amount of immediate feedback messages, which is unrealistic. We propose the idea of performing network coding on the feedback messages and show that if the intermediate node waits until receiving only one feedback message from each next-hop node, the optimal level of network coding redundancy can be computed in a distributed manner. The coded feedback messages require a small amount of overhead, as they can be integrated with the packets. Our approach is also oblivious to losses and correlations among the links, as it optimizes the performance without the explicit knowledge of these two factors

In a network that supports multiple unicast, there are several source terminal pairs; each source wishes to communicate with its corresponding terminal. In this work we consider linear network coding schemes for wired three-source, three-terminal directed acyclic networks with unit capacity edges. Each source contains a unit-entropy message that needs to be communicated to the corresponding terminal. Our achievability schemes use a combination of random linear network coding and appropriate preceding. In particular, our solutions are based either scalar codes or vector codes that operate over two time units (i.e., two network uses). This is potentially useful, as one could arrive at multiple unicast schemes for arbitrary rates by packing unit-rate structures for which our achievability schemes apply. We first investigate a two-unicast scenario with connectivity Level and rate requirement and use that in conjunction with vector network coding to address three-unicast with connectivity level. We use random linear coding and precoding at the sources to arrive at the result By Sachin prabha Ramesh.R

EDIT: The line should say "INIT: received Hello from neighbor but did not see own router ID" from 11:40 forward. In this video, we're going to discuss the OSPF neighbor states. Briefly, the OSPF states are Down, Attempt, Init, 2-Way, ExStart, Exchange, Loading, and Full. The 2-Way and Full states are stable. If a router is stuck in any other state, it indicates a problem in forming adjacencies. The Down state is the first OSPF neighbor state and means that no Hello packets have been received from a neighbor. The Attempt state is only valid for manually configured neighbors in NBMA networks. In the Attempt state, the router sends unicast Hello packets every poll interval to the neighbor, from which Hellos have not been received within the dead interval. The Init state specifies that the router has received a Hello packet from its neighbor, but the receiving router's ID was not included in the Hello packet. The 2-Way state designates that bidirectional communication has been established between the neighbors. Bidirectional means that each router has seen the other's Hello packet. This state is attained when the router receiving the Hello sees its own router ID in the received Hello packet. Possible DR/BDR election also happens in this state. In the ExStart state, the routers establish the master/slave relationship. The router with the higher router ID becomes the master and starts the exchange. In the Exchange state, the routers exchange database description (DBD) packets. The DBD packets describes the sender's link-state database by sending LSA headers to the neighbor. The neighbor can then request missing or more recent LSA from the sender. n the Loading state, the actual exchange of link state information occurs. Based on the information provided by the DBDs, routers send and request link state information. In the Full state, routers are fully adjacent with each other. All the LSAs have been exchanged and the databases are fully synchronized. Thank you for watching!

Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) are two security protocols to secure wireless computer networks. WPA was developed as a replacement to broken Wired Equivalent Privacy (WEP) in 2003, as WEP can be bypassed very easily and effectively using various methods. WPA uses RC4 stream cipher based Temporal Key Integrity Protocol (TKIP) to ensure that each data packet is transmitted with a unique encyption key, thereby preventing the types of attacks that compromised WEP. However, a flaw has been discovered on TKIP based WPA which relies on chopchop attack used in WEP cracking. TKIP is much stronger than a cyclic redundancy check algorithm (CRC) used in WEP, but not as strong as the Counter Mode Cipher Block Chaining Message Authentication Code Protocol, Counter Mode CBC-MAC Protocol (CCMP) algorithm used in WPA2. WPA2 uses Advanced Encryption Standard (AES) block cipher based CCMP. It is stronger than TKIP in both privacy and integrity. Authentication modes : 1. WPS mode 2. Personal mode 3. Enterprise mode WPS mode has already been discussed and exploited in previous video. Here is the link in case you missed it https://youtu.be/7XYt5-FeB7U PERSONAL or PSK mode was designed for home and small office networks. This mode use a 256 bit key to encrypt the network traffic, which is a string of 64 hexadecimal digits or a passphrase of 8 to 63 printable ASCII characters. If ASCII characters are used, the 256 bit key is calculated by applying the PBKDF2 key derivation function to the passphrase, using the SSID as the salt and 4096 iterations of HMAC-SHA1. Personal mode is available in both WPA and WPA2, which is the topic of this video. The authentication takes place by a 4-way handshake in both PSK and Enterprise mode. Initial authentication is done using PSK or EAP exchange to ensure the client is authenticated to the access point (AP). After PSK authentication a secret shared key is generated called Pairwise Master Key (PMK). The PSK is derived from a password that is put through PBKDF2-SHA1 as the cryptographic hash function. In a pre-shared-key network, the PSK is actually the PMK. For AP and client exchanging encrypted data, both need to have the right key(s) installed. Each time a client (Supplicant) associates to an AP (Authenticator), new Pairwise Temporal/Transient Key (PTK) is generated, which is unique for each connected client. In case of Broadcast and Multicast frames, all clients use the same Groupwise Temporal Key (GTK) that don’t require a new generation for each association. The function to generate a Pairwise Temporal Key (PTK) is known as a Pseudo Random Function (PRF): PTK = PRF(PMK + ANonce + SNonce + APMAC + SMAC) Nonce is number used once and are pseudo random numbers. Anonce and Snonce are AP and STA (client or station) nonces respectively. APMAC and SMAC are MAC addresses of AP and STA respectively. The 4-way handshake takes place as follows : 1. The AP sends Anonce to the client or STA. 2. The client sends the SNonce to the AP protected by a cryptographic hash (HMAC-SHA1) called Message Integrity Code (MIC) for integrity of this message. The message also includes the Robust Security Network Information Element (RSN IE). 3. The AP constructs and sends the GTK and a sequence number together with another MIC. 4. The Supplicant acknowledges the installation of PTK and GTK afterwards, encrypted Unicast and Broadcast/Multicast transmission can start now. Using aircrack along with a dictionary or crunch bruteforce can take from fews minutes to lifetime to crack the passkey. However, the things can be accelerated using rainbow tables, precomputed hashes, GPU power. A long random alphanumeric password containing upper and lower case letters and special characters is beyond the of computation power available till now. However no one uses such passwords instead people use passwords which are easy to remember, and hence are vulnerable to such attacks. So, in order to speeed up the cracking process what we do is that we use precomputed hashes, and hence saving the conversion time required to hash all words in a wordlist. Rainbow tables come up with precomputed hashes for most commonly used SSIDs. Remember two different SSIDs with same password will produce different hashes. So in order to use rainbow table against captured hash one must ensure first the target network's SSID is present in most commonly used 1000 SSIDs list. In case your SSID is not present in that list then you cant create your own rainbow table using tools like RainbOwCrack. We can make our own hashes for a partical SSID using genpmk and testing the created hashes against captured hash using another tool called cowpatty. In order to use GPU power we can use tools loke oclHashCat, which uses GPU power along with CPU power to crack the wifi key. I am going to cover all these topics in coming tutorials.

Airgeddon is a multi-use bash script for Linux systems to audit wireless networks. It is an all in one tool. It can run many attacks on WEP, WPS and WPA networks. About WPS WPS security flaw was found by Dominique Bongard. He found that some Access Points have flaws in the way the nonces (known as E-S1 and E-S2) are generated, that are supposed to be secret. First we need to understand how WPS exchange works. When the Registrar (the client computer) wants to connect to the Enrollee (the Access Point) they exchange a series of request and response messages as part of the negotiation process, these are named M1 to M8. In the Pixie Dust Attack, the negotiation process can be stopped right after message M3 because we already have all the values needed for the attack. The registrar sends EAPOL start message. Let’s see how WPS exchange works. Enrollee generates Enrollee Nonce or N1 and DH Public Key of Enrollee or PKE. Enrollee sends M1 message which is a concatenated string of N1, description and PKE. Upon reception of M1 the Registrar generates PKR and N2. The Registrar computes the DHKey using SHA-256 and calculate the Key Derivation Key. Finally AuthKey, KeyWrapKey, and EMSK are derived and the M2 response message is sent. The M2 message is a concatenated string of N1, N2, description, PKR and Auth. The M3 request message is sent by Enrollee which is again a concatenated string of E-HASH1 and E-HASH2, that is WPS PIN in hashed form, in order to prove that it also knows the PIN, and the client is not connecting to a rouge Access Point. The real fun starts now, the E-HASHes are calculated by H-MAC-SHA-256 with auth key using E-S1 and E-S2, PSK1 an PSK2, PKE and PKR. Now in each hash we have two unknowns, the E-S1 and E-S2 ( or 128 bit random nonces), PSK1 and PSK2 or the first and second halves of the pin. Now, if we know the nonces generated by pseudo-random generators (PRNG), we can brute force PSK1 and PSK2 as each of these contain 4 digits of pin. if PRNG state can be recovered, E-S1 and E-S2 can be calculated and PSK1 and PSK2 be brute forced from E-Hash1 and E-Hash2. These E-S1 and E-S2 are essentially the "keys to unlock the lock box" containing the WPS pin. After this, we use reaver or bully to connect to the access point using pin, which in turn throws back the credentials. I am not going to explain how this exchange works, if you want to know in detail leave a comment. 4Way Handshake In WPA-PSK, 4way handshake starts immediately after Open System Authentication & Association state finish. Message 1. Authenticator sends EAPOL-Key frame containing an A-Nonce( or Authenticator nonce) to supplicant. The frame includes the authenticators mac address. Message 1 is sent without any protection. With this information, supplicant have all necessary input to generate PTK using PMK, A-Nonce, S-Nonce, Authenticator MAC Address, and Supplicant MAC Address. This is used to encrypt all unicast transmission between client & Access Point. Message 2. Supplicant sends an EAPOL-Key frame containing S-Nonce to the Authenticator. Now authenticator has all the inputs to create PTK. Supplicant also sent RSN-IE capabilities to Authenticator & MIC. Authenticator derive PTK & validate the MIC as well. Message 3. If necessary, Authenticator will derive GTK. Authenticator sends EAPOL-Key frame containing A-Nonce, RSN-I E & MIC. GTK will be delivered (encrypted with PTK) to supplicant. It contains message to supplicant to install temporal keys. Message 4. Supplicant sends final EAPOL-Key frame to authenticator to confirm temporal keys have been installed with MIC. Let's see how password cracking works. PTK is concatenation of five different keys. Key Confirmation Key or KCK, Key Encryption Key or KEK, Temporal Encryption Key or TEK and two MIC keys. KCK is used to construct MIC in EAPOL packets 2,3 and 4. 4-way handshake password "cracking" works by checking MIC in the 4th frame. 4-way handshake is parsed to get MAC addresses, nonces, and EAPOL payload and MIC from 4th frame. Words from dictionary are used to compute PMK. PTK is computed from PMK, MAC addresses and nonces. KCK from computed PTK is used to compute MIC. Computed M I C is compared to the genuine MIC. If they match, then password is reported as correct. Evil Twin with Captive Portal MDK3 process kicks all the clients from the target access point, so they can be lured to connect to the fake access point, and enter the WPA password. A fake DNS server is launched in order to capture all the DNS requests and redirect them to host running the script. A captive portal is launched in order to serve a page to all the clients, which prompts all the users to enter their password. Each submitted password is verified against the handshake captured earlier.

Securing data and communications requires suitable encryption key protocols. In this paper, we propose a certificateless-effective key management (CL-EKM) protocol for secure communication in dynamic WSNs characterized by node mobility. The CL-EKM supports efficient key updates when a node leaves or joins a cluster and ensures forward and backward key secrecy. The protocol also supports efficient key revocation for compromised nodes and minimizes the impact of a node compromise on the security of other communication links. A security analysis of our scheme shows that our protocol is effective in defending against various attacks.We implement CL-EKM in Contiki OS and simulate it using Cooja simulator to assess its time, energy, communication, and memory performance.

In this short video I show a brief overview of the step by step requirements to create a VPN between a Cisco IOS using VTI and FortiGate 5.2.x track using 0.0.0.0/0.0.0.0 Quick mode selectors (Single P2) Reason to configure your Cisco with this type of VPN: • Simplifies management---Customers can use the Cisco IOS® Software virtual tunnel constructs to configure an IPSec virtual tunnel interface, thus simplifying VPN configuration complexity, which translates into reduced costs because the need for local IT support is minimized. In addition, existing management applications that can monitor interfaces can be used for monitoring purposes. • Supports multicast encryption---Customers can use the Cisco IOS Software IPSec VTIs to transfer the multicast traffic, control traffic, or data traffic---for example, many voice and video applications---from one site to another securely. • Provides a routable interface---Cisco IOS Software IPSec VTIs can support all types of IP routing protocols. Customers can use these VTI capabilities to connect larger office environments---for example, a branch office, complete with a private branch exchange (PBX) extension. • Improves scaling---IPSec VTIs need fewer established security associations to cover different types of traffic, both unicast and multicast, thus enabling improved scaling. • Offers flexibility in defining features---An IPSec VTI is an encapsulation within its own interface. This offers flexibility of defining features to run on either the physical or the IPSec interface.

Broadcast Domains & CSMA/CA In networking, Layer-2 hardware, including switches, Access points & bridges, are programmed to forward Broadcast Message so as to reach all Hosts on the LAN. The area over which a Broadcast message reaches is known as the Broadcast Domains, which is synonymous with the size of the Local Area Network. Because the Broadcast Domain represents the interconnected topology of layer-2 equipment, more Switches, Access Points, and Bridges equates to a larger Broadcast Domain. By comparison, however, Routers do not forward Broadcast Messages, and therefore mark the boundaries of the Broadcast Domain, that is, the LAN. When the Broadcast Domain becomes too large or populous, Broadcast Messages lead to Broadcast Storms, where normal Host traffic causes LAN performance to suffer tremendously, noting increased latency and reduced throughput. A good rule of thumb is to limit the size of a LAN to no greater than a couple hundred Network Devices, before building another Network Segment and Range. Building a new LAN is as simple as adding another Router, with new LAN interfaces. However, a more cost-effective, practical way to add additional Network Segments and Ranges is to implement Virtual LANs on existing Network Devices. As more Local Networking continues to trend toward mobile computing, Wireless Design & planning for Networks becomes increasingly more important. Like Switches, Access Points expand the Broadcast Domain, but face a unique challenge, since Wireless Stations in the same proximity, by design, compete for shared access to the Wireless Channel over which they transmit. Whenever two Wireless Stations attempt to transmit over top of each other, a collision can result at nearby Receiver Radios, necessitating a retransmission. In order to reduce the chance of collisions, the 802.11 Wireless protocol relies on Carrier Sense Multiple Access / Collision Avoidance, or CSMA/CA for short, which basically requires Wireless Stations “Listen before Talk”. If the Wireless Channel is occupied, wait, then listen again before transmitting. Despite reducing collisions, CSMA/CA is an imperfect access method, as seen in scenarios involving Hidden Nodes, where a receiver hears two transmitters, but the transmitters cannot hear each other, whether due to proximity or physical obstructions. And although mechanisms like Request-to-Send, Clear-to-Send, mitigate the effect of Hidden Nodes, CSMA/CA remains an imperfect access method, with upper limits on the density and volume of stations in a wireless coverage area.

This project is a demonstration of how we can set up a client-server architecture to allow for secure file transfers between multiple parties, as well as store it persistently on a cloud storage. Now, while storing encrypted files is a relatively easy task, we also ensure that the server-side user, either malicious or legitimate, is unable to decrypt the files even after snooping through the network traffic. We've proposed the use of a modified version of the Diffie-Hellman key exchange protocol, wherein more than two parties can arrive at a shared key. We also use public-key encryption to authenticate users before the key exchange, so that man-in-the-middle attacks are completely mitigated. In this video, we demonstrate the different components developed to set up this architecture. The first component registers the individual users onto the cloud service. The second component sets owner-access permissions to the files uploaded by the users, to be accessible by both the creator and the collaborating users. The third component is a notification system which allows for sending multicasted updates to owners of a particular file. It also supports sending unicast messages to individual users. Moreover, we support persistent queuing of messages, so that if a user is sent messages while he or she is offline, the messages will be delivered and flushed from the server only after that user logs in and pulls those messages. The fourth component handles the actual end-to-end encryption of the files, and transferring them to the server's persistent storage. Key exchange protocols as well as user authentication mechanisms take place between the server and the client before any further communications. Also, to negotiate the shared key for collaborated files, a modified version of the popular key exchange protocol (Diffie-Hellman Key Exchange Algorithm) is used to distribute keys to different users. To consolidate all of this for a user, we've built a custom terminal emulator that supports only certain whitelisted commands. All other commands are immediately rejected to prevent unauthorized use of the application. (For example, `sudo rm /` won't delete my entire file system. xD) This project was developed by a team of three - Ayush Soni, Reuben John, and Soorya Annadurai. We're all third-year Computer Science students in Manipal Institute of Technology, India. This is an open-source project, and you can find the project here: https://github.com/three-horsemen/sftp If you have any ideas or suggestions, do let us know in the comments! We'll definitely try adding or improving this architecture. Thanks for watching!

In terms of packet scheduling, our goal is to minimize the localization time, and to do so we consider two packet transmission schemes, namely a collision-free scheme (CFS), and a collision-tolerant scheme (CTS). The required localization time is formulated for these schemes, and through analytical results and numerical examples their performances are shown to be dependent on the circumstances. When the packet duration is short (as is the case for a localization packet), the operating area is large (above 3 km in at least one dimension), and the average probability of packet-loss is not close to zero, the collision-tolerant scheme is found to require a shorter localization time. At the same time, its implementation complexity is lower than that of the collision-free scheme, because in CTS, the anchors work independently. CTS consumes slightly more energy to make up for packet collisions, but it is shown to provide a better localization accuracy. An iterative Gauss-Newton algorithm is employed by each sensor node for self-localization, and the Cramér Rao lower bound is evaluated as a benchmark.

What is SECURE MULTICAST? What does SECURE MULTICAST mean? SECURE MULTICAST meaning - SECURE MULTICAST definition - SECURE MULTICAST explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ IP Multicast is an internet communication method where a single data packet can be transmitted from a sender and replicated to a set of receivers. The replication techniques are somewhat dependent upon the media used to transmit the data. Transmission of multicast on an inherent broadcast media such as Ethernet or a satellite link automatically allows the data packet to be received by all the receivers directly attached to the media. In contrast, transmission of multicast on media that is point-to-point or point-to-multipoint requires the packet to be replicated for each link. The replication process should occur in an optimal manner where a distribution tree is built within the network. The packet can be replicated at each of the branches in the tree. This mitigates the requirement for the sender to replicate the packet once for each recipient. The use of IPsec as a communication link requires a point-to-point connection establishment. Usually, the security is required from sender to receiver which implies the sender must replicate the packet on each of the secure connections - one for each receiver. As the number of receivers grows, the sender must scale by replicating the packet to each of the receivers. The processing load placed on the sender can be high which limits the scalability of the sender. A new method was required to securely transmit multicast and this was referred to as Secure Multicast or Multicast Security. The Internet Engineering Task Force (IETF) created a new Internet Protocol (IP) to securely transmit multicast traffic across a packet network. The protocol definition was developed in the Multicast Security Workgroup and led to several Request for Comments (RFC) that are now used as standards for securing IP multicast traffic. The protocol allowed a sender to encrypt the multicast packet and forward it into the packet network on the optimal distribution tree. The packet may be replicated at the optimal locations in the network and delivered to all the receivers. The receivers are capable of decrypting the packet and forwarding the packet in the secure network environment. The sender of a multicast packet does not know the potential receivers; therefore, the creation of pair-wise encryption keys (one for each receiver) is impossible. The sender must encrypt packets using a shared key that all the legitimate receivers use to decrypt the packets. The security of the system is based on the ability to control the distribution of the keys only to those legitimate receivers. For this, the IETF created the Group Domain of Interpretation (GDOI) protocol defined in RFC-6407. The protocol allows the sender and receiver to join a key server where policies and keys are encrypted and distributed to the members of the secure multicast group. The key server can authenticate and authorize senders and receivers into a specific group where the shared key is used to encrypt and decrypt traffic between members of the group.

However, most of the existing anonymous fingerprinting protocols are impractical for two main reasons: 1) the use of complex time-consuming protocols and/or homomorphic encryption of the content, and 2) a unicast approach for distribution that does not scale for a large number of buyers. This paper stems from a previous proposal of recombined fingerprints which overcomes some of these drawbacks. However, the recombined fingerprint approach requires a complex graph search for traitor tracing, which needs the participation of other buyers, and honest proxies in its P2P distribution scenario. This paper focuses on removing these disadvantages resulting in an efficient, scalable, privacy-preserving and P2P-based fingerprinting system.

Optimal Configuration of Network Coding in Ad Hoc Networks TO GET THIS PROJECT IN ONLINE OR THROUGH TRAINING SESSIONS CONTACT: Chennai Office: JP INFOTECH, Old No.31, New No.86, 1st Floor, 1st Avenue, Ashok Pillar, Chennai – 83.

In particular, physical-layer NC and random linear NC are adopted in static and mobile ad hoc networks (MANETs), respectively. Furthermore, we characterize the goodput and delay/goodput tradeoff in static networks, which are also analyzed in MANETs for different mobility models (i.e., the random independent and identically distributed (i.i.d.)mobility model and the random walk model) and transmission schemes (i.e., the two-hop relay scheme and the flooding scheme). Moreover, the optimal configuration of NC, which consists of the data size, generation size, and NC Galois field, is derived to optimize the delay/ goodput tradeoff and goodput. The theoretical results demonstrate that NC does not bring about order gain on delay/goodput tradeoff for each network model and scheme, except for the flooding scheme in a random i.i.d. mobility model. However, the goodput improvement is exhibited for all the proposed schemes in mobile networks. To our best knowledge, this is the first work to investigate the scaling laws of NC performance and configuration with the consideration of coding overhead in ad hoc networks.
