In this paper, a secure voice communication system based on TMS320VC5410 is proposed, which includes the hardware design and the software design. Among them, the A/D and D/A conversions of voice signals are implemented by the MC145480, while data transmission is performed by the TL16C554. A chaotic voice encryption algorithm combining cat map and logistic map is implemented in this system. Experiments of both encrypted and non-encrypted voice communication over short distance have been performed, which demonstrates the feasibility of the proposed system.
