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…
New Results on Multiple-Input Multiple-Output Broadcast Channels with Confidential Messages
Ruoheng Liu, Tie Liu, H. Vincent Poor +1
This paper presents two new results on multiple-input multiple-output (MIMO) Gaussian broadcast channels with confidential messages. First, the problem of the MIMO Gaussian wiretap…
MIMO Gaussian Broadcast Channels with Confidential and Common Messages
Ruoheng Liu, Tie Liu, H. Vincent Poor +1
This paper considers the problem of secret communication over a two-receiver multiple-input multiple-output (MIMO) Gaussian broadcast channel. The transmitter has two independent,…
Fading Cognitive Multiple-Access Channels With Confidential Messages
Ruoheng Liu, Yingbin Liang, H. Vincent Poor
The fading cognitive multiple-access channel with confidential messages (CMAC-CM) is investigated, in which two users attempt to transmit common information to a destination and us…
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…
