Abstract The encryption equipment for dynamic secret communication is a security equipment which is established on the "one-time" system of cryptography and connected in the transmitting and receiving terminal circuit. It is formed from synchronous circuit, A/D converter circuit, operational circuit, double-trace random digital code disk, random digital code detection head, detection head feeding mechanism, main shaft motor, speed changer, cipher question-answering circuit system, synchronous correction system and regulated supply, etc.. Said invention uses the synchronous movement of detection heads of transmitting and receiving both sides on the respective double-trace random digital code disks to implement encryption and decryptment of source file. It features high reliability, strong universality, good exclusive and high automation.
