High Security SCMA Encryption Scheme Based on Codebook and Frequency Masking in Seven Core Fiber

A high security SCMA encryption scheme based on codebook and frequency masking in seven core fiber was proposed. The 7D cellular neural network (CNN) is used for codebook encryption and carrier frequency encryption. The experimental results show that the proposed signal encryption scheme will not lead to significant signal degradation and it can effectively ensure the safety performance of the system.
