In this paper, for physical-layer security(PLS), a novel scheme of polar coding encryption is introduced in the wiretap channel(WTC) model. To decrease transmission overhead of the shared secret information and enhanc...
This paper analyzed the security of constant dimensional subspace code against wiretap attacks. The security was measured in the probability with which an eavesdropper guessed the source message successfully. With the...

Under the assumption that the wiretapper can get at most r(r < n) independent messages, Cai et al. showed that any rate n multicast code can be modified to another secure network code with transmitting rate n- r by a ...
