A transmitting means for transmitting encrypted data, and a receiving means for receiving encrypted data are coupled to the plurality of ciphering means. The control means automatically determines which of the ciphering means to employ for any given secure communication. The method for establishing a secure communications link includes the steps of exchanging a first message for determining a common key generation and ciphering method and comparing a further shared message for validation of communications terminal security. Additionally, the steps of trading a still further message for providing data to form traffic keys to initialize key generators, interchanging an additional message for synchronizing and verifying synchronization of secure communications between secure communications terminals, and initiating secure communication are used.Other References
