FPGA-Based Voice Encryption Equipment under the Analog Voice Communication Channel

This paper describes a voice encryption device that can be widely used in civil voice call encryption. This article uses a composite encryption method to divide the speech into frames, rearrange them in the time domain, and encrypt the content of the frames. The experimental results show that the de...
