Description

In wireless communications, chaotic encryptions at the physical layer provide enhanced security. Recent study has reported that the chaotic encryption works within a massive MIMO (Multiple-Input Multiple-Output) using Belief-Propagation decoding. However, decoding accuracy of this framework is relatively low since the encryption may position the constellation points close to each other. To address this, we propose a new chaotic encryption that keeps a certain distance between constellation points. We numerically evaluate decoding accuracy and security performance of the framework with proposed encryption. The results suggest that the new framework decreases bit error rate and enhances security.
