%X With regard to communication security,the safekeeping of password and real-time processing in speech signal encryption based on triple Data Encryption Standard(3DES) were analyzed.In addition,the basic framework of speech encryption and the hardware system design in encryption telephone were presented.The functional module of system software was designed and the compiled program was loaded into the FPGA.The encryption telephone was validated in the public telephone net.This research indicates that the encryption functional module can be applied to point-to-point speech communication and other low speed data traffic.
