A Broadcast Approach To Secret Key Generation Over Slow Fading Channels
Xiaojun Tang, Ruoheng Liu, Predrag Spasojevic +1
A secret-key generation scheme based on a layered broadcasting strategy is introduced for slow-fading channels. In the model considered, Alice wants to share a key with Bob while k…
Interference Assisted Secret Communication
Xiaojun Tang, Ruoheng Liu, Predrag Spasojevic +1
Wireless communication is susceptible to eavesdropping attacks because of its broadcast nature. This paper illustrates how interference can be used to counter eavesdropping and ass…
The Gaussian Wiretap Channel with a Helping Interferer
Xiaojun Tang, Ruoheng Liu, Predrag Spasojevic +1
Due to the broadcast nature of the wireless medium, wireless communication is susceptible to adversarial eavesdropping. This paper describes how eavesdropping can potentially be de…
Interference-Assisted Secret Communication
Xiaojun Tang, Ruoheng Liu, Predrag Spasojevic +1
Wireless communication is susceptible to adversarial eavesdropping due to the broadcast nature of the wireless medium. In this paper it is shown how eavesdropping can be alleviated…
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…
