Abstract. We re-visit the problem of perfectly secure message transmission (PSMT) in a directed network under the presence of a threshold adaptive Byzantine adversary, having unbou...
In a classic paper, among a multitude of other security issues, Claude E. Shannon defined perfect secrecy for a pair of secure computers communicating over an insecure link. The ...

Abstract-- We study the Gaussian multiple-input multipleoutput (MIMO) wiretap channel, which consists of a transmitter, a legitimate user, and an eavesdropper. In this channel, the...
