发明名称 CRYPTOGRAPHIC VOICE COMMUNICATION
摘要 A cryptographic communication system encrypts digital information to be transmitted by combination with a digital one time key derived from an optical digital disk. The system can run on standard microcomputers and includes an initialisation routine whereby a common initial address for both transmit and receive disks is settled by an arbitration technique based on last recorded disk positions.
