PROJECT TITLE :

Physical Integrity Check in Cooperative Relay Communications

ABSTRACT:

We tend to propose a physical-layer technique for checking the integrity of data provided by an intermediate node (relay) in cooperative relay Communication systems. The proposed approach, built on the theory of likelihood ratio take a look at, exploits the physical-layer signal from the source in detecting any information modification (false data injection attack) made by the relay. We tend to present the optimum detection methodology that minimizes the tip-to-end outage chance and therefore the minmax detection methodology that minimizes the most potential outage likelihood beneath unknown attack likelihood. We tend to show that the optimum detection technique can offer nearly the identical end-to-end outage chance which will be provided by the best cryptographic technique that perfectly detects the false injection at the expense of high computational cost and bandwidth overhead. The proposed physical integrity check will be used as an additional layer of protection or will complement to the standard cryptographic techniques.
