Secure Polar Coding for Adversarial Wiretap Channel
Yizhi Zhao
The adversarial wiretap channel (AWTC) model is a secure communication model in which adversary can directly read and write the transmitted bits in legitimate communication with fi…
Secure Polar Coding with Delayed Wiretapping Information
Yizhi Zhao, Hongmei Chi
In this paper, we investigate the secure coding issue for a wiretap channel model with fixed main channel and varying wiretap channel, by assuming that legitimate parties can obtai…
A Proof of Non-stationary Channel Polarization
Yizhi Zhao, Hongmei Chi, Shiwei Xu +2
In this letter, we consider the proof of non-stationary channel polarization theory. First we construct a multi-channel stochastic process for the non-stationary channel polarizati…
CSI Learning Based Active Secure Coding Scheme For Detectable Wiretap Channel
Yizhi Zhao
In this paper, we consider the problem of secure and reliable communication with uncertain channel state information (CSI) and present a new solution named active secure coding whi…
