Generation of Secret Key for Physical Layer to Evaluate Channel Characteristics in Wireless Communications
This manuscript aims to generate a secret key for a PHY layer to evaluate the channel characteristics in wireless communications. An algorithmic approach is adopted for multimedia encryption to generate a secret key between two entities communicating with each other in a real time simulation environment such as MATLAB. Two classes of PHY key generation schemes are analyzed for designing the alg...
متن کاملPhysical Layer Key Generation: Securing Wireless Communication in Automotive Cyber-Physical Systems
Modern automotive Cyber-Physical Systems (CPS) are increasingly adopting wireless communications for Intra-Vehicular, Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) protocols as a promising solution for challenges such as the wire harnessing problem, collision detection, and collision avoidance, traffic control, and environmental hazards. Regrettably, this new trend results in new...
متن کاملPhysical-Layer-Enhanced Wireless Secret Key Exchange
We address the problem of efficiently establishing a shared secret key over an open wireless channel in the presence of an active (jamming) adversary. A commonly employed technique in practice for key sharing is the cryptographic ellipticcurve Diffie-Hellman (DH) protocol; however, its communication cost in a jammed environment is very high. Hence, we employ novel physical-layer techniques to e...
متن کاملMaster Synchronization in Physical-Layer Communications of Wireless Sensor Networks
Synchronization in physical layer of wireless sensor networks is critical in restricting complexity of tag node and power consumption. Considering the master-to-tag communication (i.e., receiving signal from a master or anchor node by tag nodes), we propose a scheme on the basis of the principles of feedback control, to transfer the signal acquisition functionality from the tag receivers to the...
متن کاملComputation-efficient key establishment in wireless group communications
Efficient key establishment is an important problem for secure group communications. The communication and storage complexity of group key establishment problem has been studied extensively. In this paper, we propose a new group key establishment protocol whose computation complexity is significantly reduced. Instead of using classic secret sharing, the protocol only employs a linear secret sha...
