Secret Message Transmission by HARQ with Multiple Encoding [PDF]
, 2014 Secure transmission between two agents, Alice and Bob, over block fading channels can be achieved similarly to conventional hybrid automatic repeat request (HARQ) by letting Alice transmit multiple blocks, each containing an encoded version of the secret

Enhancing Physical Layer Security of DF Buffer-Aided Relay Networks With Small Buffer Sizes
IEEE Access, 2019 In this paper, we propose a novel max-weight secure link selection (MWSLS) scheme to enhance physical layer security of decode-and-forward (DF) buffer-aided relay networks. The MWSLS scheme can select the link with the largest weight among all secure and
