Abstract

In order to solve the security problem for fading channel, a pragmatic physical layer encryption (PLE) scheme is proposed, which utilizes diversity technique elaborately. Different from the conventional PLE schemes based on phase rotation for modulated symbol, the proposed scheme changed phase and amplitude together for a block of symbols each time, which can be defined as multi-dimensional PLE (MPLE). Unconventional constellation obfuscates eavesdropper, which can be seen as the first level security in physical layer. The correct probability based on chosen plaintext attacks (CPA) and known plaintext attacks (KPA) are deduced. It can be seen from the simulation results that the MPLE scheme can achieve lower attack success probability because of multi-level security and better performance based on diversity under fading channel.
