Employing traditional wireless two-hop relaying is very easy for eavesdropper to overhear message due to the broadcasting nature of transmission. However, relays, which are equipped with caching capabilities to store popular content, can serve the destination directly without fetching messages from source. In order to improve physical layer security, the design of hybrid cache placement becomes more...
We investigate the impact of cochannel interference on the security performance of multiple amplify-and-forward (AF) relaying networks, where $N$ intermediate AF relays assist the data transmission from the source to the destination. The relays are corrupted by multiple cochannel interferers, and the information transmitted from the relays to the destination can be overheard by the eavesdropper. In...
