Item Security solutions against attacks in mobile ad hoc networks and their verification using BAN logic(IEEE, 2017) Dua, AmitIn the last few years, there has been tremendous interest in ad hoc wireless networks as they have massive military and commercial potential. An ad hoc wireless network serves as an independent network that comprises of mobile devices that utilize wireless transmission for communication, having no fixed infrastructure. These networks eliminate the complexity of infrastructure setup and hence can be deployed in quick time. However, on the negative side, such networks are very vulnerable to attacks against availability, service integrity, security, privacy and several other possible threats. To overcome these attacks, several security mechanisms have been proposed to ensure the reliability of ad hoc networks.Item Bloom filter based efficient caching scheme for content distribution in vehicular networks(IEEE, 2019) Dua, AmitWith the progression of Internet of Things (IoT), the number of connected vehicles in smart cities have shown an exponential growth. In order to enable fast data transfer, these vehicles communicate with each other and the roadside units. However, the data generated by these connected vehicles has overwhelming increased in recent times, which in turn overloads the traditional host-centric approach. For this reason, vehicular content-centric networking (VCCN) has emerged as a revolution, which provides efficient content distribution among vehicles. However, cache management is one of the most important aspects, which needs to be handled effectively. Therefore, in this paper, a bloom filter-based cache management scheme is proposed to enhance the performance of data transfer between smart connected vehicles. This algorithm uses the functionality of cache in vehicles to enable cooperative content distribution. The evaluation of bloom filter-based cache management scheme shows that the bloom filter reduces the search time in contrast to other data structures, which in turn increases the efficiency of retrieval from cache. The simulation results show that the proposed scheme achieves faster retrieval time and an efficient allotment system for helper vehicles in a smart city environment.Item Decentralized Online Voting using Blockchain and Secret Contracts(IEEE, 2021) Bhatia, AshutoshVoting is a complex process with a lot depending on it. Building an e-voting system that can guarantee anonymity, verifiability, and transparency together is a challenging task. Continuous efforts are being made to improve the voting system to achieve these properties. Recently, blockchain has hit the technology space with many promises, especially to make verifiable and transparent decentralized systems. However, a major challenge faced with blockchain-based e-voting systems is to achieve the users' anonymity while ensuring only authorized voters should be able to vote, and that too only once. To address these issues, this paper proposes a blockchain-based e-voting system with secret contracts. We have used Enigma (a secure multiparty computation platform) to design secret contracts. The proposed system meets most of the features required to conduct free and fair voting electronically.Item Covert channel in IPv6 Destination option Extension header(IEEE, 2014) Mavani, MonaliIPv6 is next generation Internet protocol whose market is going to increase as IPv4 addresses are exhausted and more mobile devices are attached to Internet. The experience with IPv6 protocol is less as its deployment is slow. So there are many unknown threats possible in IPv6 networks. One such threat addressed in this paper is covert communication in the network. Covert channel is way of communicating classified information. In network it is done by network protocol's control fields. Destination option Extension header of IPv6 is used to pass secret information which is shown experimentally in real test network set up. For creation of attack packets Scapy-Python based API is used. Covert channel due to unknown option and nonzero padding in PadN option is shown. Their detection is also proposed and detector logic is implemented using shell scripting and C programming.Item ATM Networks: Concepts and Protocols(McGraw Hill, 2006) Narang, NishitNetworking technologies are playing a pivotal role in ‘networking’ our world. Among the networking technologies that are relevant today, ATM is one of the most popular and pervasive as it seamlessly integrates local area networks and wide area networks. Further, as it provides a single platform for voice, video and data, it facilitates convergence. ATM Networks: Concepts and Protocols is a single-stop reference on this technology. The revised edition of this book covers the relevant concepts, the three layers of ATM protocol reference model, core concepts of ATM networks (including signaling, routing and traffic management), interworking aspects and the application of ATM networks.Item 3G Mobile Networks: Architecture, Protocols and Procedures(McGraw Hill, 2004) Narang, NishitIn India, the mobile subscriber baser is increasing at a phenomenal rate. After the successful adoption of Second Generation (2G) Technology GSM and 2.5G Technology GPRS, the industry is now rapidly moving towards Third Generation (3G) Networks. The book, written by two young engineers, touches almost every imaginable aspect of a 3G Network, spanning across topics such as: • UMTS Network Architecture (including Access Network and Core Network), • Protocols (including RRC, NBAP, RANAP, MM/GMM, MAP and GTP), • Procedures (including UTRAN Procedures, Mobility Management, Call/Session handling and Security Management), and • Services (including Supplementary Services and Value-added Services). Also the book covers topics like IP Multimedia Sub-system (IMS) and SIGTRAN. Besides these, the book includes the status of deployment of 3G UMTS Networks across the world and provides a brief introduction to 4G Networks setting the tone for future advancements. With this coverage, the book would serve the needs of telecom engineers and students.Item Collaborative Neighbor Discovery with Slow Scan for Directional Sensor Networks(IEEE, 2018) Gudino, Lucy J.Neighbor discovery forms a vital part of Medium Access Control (MAC) and routing protocols in Directional Sensor Network (DSN). Discovering neighbors in DSN is a challenging task due to limited coverage of directional antennae. The Collaborative Neighbor Discovery (COND) protocol suggests a time-efficient mechanism to discover neighbors but fails to discover all the neighbors. In this paper, we propose an improvement over COND protocol by employing Slow-Scan (SS) mode, which sets different nodes in SS mode at different time intervals. This model named COllaborative Neighbor Discovery with Slow Scan (COND-SS) aims to discover all the nodes in the network. The simulation results reveal that the COND-SS protocol has lower latency and it improves the neighbor discovery ratio considerably up to 100%.

But achieving both simultaneously is challenging. In this work, we consider UAV device authentication as a use case and develop a fast and secure UAV device authentication system. Our key idea is to leverage highly secure Physically Unclonable Functions (PUFs) and high-speed programmable packet-processing data planes, and develop a practically deployable PUF-based authentication protocol for UAVs that is (a) robust to various security attacks, and (b) enables UAV authentication at network speed. In this work, we demonstrate the feasibility of our idea by offloading the authentication protocol to a Tofino-based highspeed programmable switch. Our preliminary experiments show that protocol offloading would reduce authentication latency significantly (approx. 100 %)
