In this paper, we present our study of an Eigenvector-based artificial noise-based jamming technique developed to provide increased wireless physical layer security in transmit-receive diversity systems and analyze the impact of channel estimation errors on system performance. Our simulation results showed that with knowledge of perfect channel state information, the technique provided secrecy capacity...
Wireless communication between two nodes in a multi-path, multi-hop network does not require that the forward transmission path and the reverse one are the same. However, if a physical-layer security scheme based on mutual channel-state-information (CSI) is used, they at least have to make sure that they use the same channels for secret-key generation. A protocol is proposed in this paper to achieve...
The fading cognitive multiple-access channel with confidential messages (MAC-CM) is investigated, in which two users attempt to transmit common information to a destination and user 1 also has confidential information intended for the destination. User 1 views user 2 as an eavesdropper and wishes to keep its confidential information as secret as possible from user 2. The multiple-access channel (both...
