Abstract: Voice encryption plays an important role in communication security technology. When confidential voice communication is involved in party, government, military and other confidential departments and civilian fields, various methods are used to encrypt voice. It is very effective to encrypt the voice before entering the transmission equipment so as to reduce the risk of secret information interception caused by communication line eavesdropping. This paper builds the hardware platform with STM32 chip as the core, studies and designs the universal encryption device for voice encryption before sending and receiving voice, clarifies the working principle of the module, and proves the effectiveness of the module in voice encryption processing on the basis of a large number of software and hardware. The realization of voice encryptorhas good encryption strength and strong versatility. As a low-cost voice encryption method, it has a wide range of application in civil applications.
