Channel-Aware Randomized Encryption and Channel Estimation Attack

IEEE Access, 2017
In this paper, we study the channel-aware (CA) randomization for a simple physical-layer encryption scheme and show that the probability of successful attack becomes very low by CA randomization when the known plain-text attack is carried out.
