On the Throughput of Secure Hybrid-ARQ Protocols for Gaussian Block-Fading Channels
Xiaojun Tang, Ruoheng Liu, Predrag Spasojevic +1
The focus of this paper is an information-theoretic study of retransmission protocols for reliable packet communication under a secrecy constraint. The hybrid automatic retransmiss…
Multiple Access Channels with Generalized Feedback and Confidential Messages
Xiaojun Tang, Ruoheng Liu, Predrag Spasojevic +1
This paper considers the problem of secret communication over a multiple access channel with generalized feedback. Two trusted users send independent confidential messages to an in…
Secure Nested Codes for Type II Wiretap Channels
Ruoheng Liu, Yingbin Liang, H. Vincent Poor +1
This paper considers the problem of secure coding design for a type II wiretap channel, where the main channel is noiseless and the eavesdropper channel is a general binary-input s…
Discrete Memoryless Interference and Broadcast Channels with Confidential Messages: Secrecy Rate Regions
Ruoheng Liu, Ivana Maric, Predrag Spasojevic +1
We study information-theoretic security for discrete memoryless interference and broadcast channels with independent confidential messages sent to two receivers. Confidential messa…
