channel envelope differencing eliminates secret key correlation lora based key generation in low power Wide Area Networks
IEEE Transactions on Vehicular Technology, 2018Co-Authors: Junqing Zhang, Alan Marshall, Lajos HanzoAbstract:This correspondence paper presents automatic key generation for long-range wireless communication in low power Wide Area Networks (LPWANs), employing LoRa as a case study. Differential quantization is adopted to extract a high level of randomness. Experiments conducted both in an outdoor urban environment and in an indoor environment demonstrate that this key generation technique is applicable for LPWANs and shows that it is able to reliably generate secure keys.

Key Management for Secure Multicast in Hybrid Satellite Networks
2014Co-Authors: Ayan Roy-chowdhury, John S. BarasAbstract:Keywords: This paper proposes a design for key management for secure multicast in hybrid satellite Networks. Communication satellites offer an efficient way to extend IP multicast services for groups in Wide-Area Networks. In order to be commercially viable, the multicast traffic should be accessible only to paying subscribers. Access control can be achieved by data encryption. This requires secure and efficient methods to generate, distribute and update the keys. Most current key management protocols do not scale well when applied to large dynamic groups in Wide-Area Networks. This paper attempts to solve the above problem for groups in a hybrid network that is composed of terrestrial Ethernet LANs interconnected by ATM-based satellite channels. We investigate current group key management protocols, and design a framework for secure and scalable key management for the multicast routing architecture in the satellite network. The proposed framework is presented in detail, alongwith analysis and simulation results. Satellite network, secure multicast, group key management. 1

IP Routing and Key Management for Secure Multicast in Satellite ATM Networks
2003Co-Authors: Ayan Roy-chowdhuryAbstract:This thesis proposes a design for secure IP multicast in hybrid satellite Networks. The emergence of IP multicast for Internet group communication has placed focus on communication satellites as an efficient way to extend IP multicast services for groups with distributed membership in Wide-Area Networks. This poses interesting challenges for routing and security. Satellite Networks can have both wired and wireless links and also different link-layer technologies like Ethernet and ATM. No proposed IP multicast routing protocol for wired Networks offers an integrated solution for such Networks. From the security viewpoint, in order to be commercially viable, the multicast traffic should be accessible only to legitimate receivers. Access control can be achieved by data encryption, with the correct decryption keys provided to authorized members. This requires secure and efficient methods to generate, distribute and update the keys. Most current key management protocols do not scale well when applied to large dynamic groups operating in Wide-Area Networks. This thesis attempts to solve the above problems and proposes a design for secure multicast in Wide-Area Networks that have terrestrial Ethernet LANs interconnected by ATM-based satellite channels. The thesis reviews the multicast services offered by IP and ATM, and proposes a multicast routing framework for the hybrid satellite network. The thesis also looks at current group key management protocols, and designs a scheme for secure and scalable key management for the proposed multicast routing architecture. The frameworks are presented in detail, followed by analysis and simulation results

distributed database systems in high speed Wide Area Networks
IEEE Journal on Selected Areas in Communications, 1993Co-Authors: S Banerjee, C WangAbstract:The issues involved in developing a distributed database system (DDBS) in a high-speed environment are discussed. The inadequacy of existing database protocols in utilizing the gigabit network is described. A concurrency control protocol that performs better than traditional DDBSs in high-speed Networks is developed. Both analytical and simulation results are presented. The focus is on the concurrency control aspect of DDBS since this protocol is at the heart of the overall functioning of the distributed system. >
