A method for establishing a secure communications link (100) includes the steps of exchanging a first message (211) for determining a common key generation and ciphering method and comparing (237) a further shared message for validation of communications terminal (103, A, 109, B) security. Additionally, the steps of trading (250) a still further message for providing data to form traffic keys to initialize key generators, interchanging (270) an additional message for synchronizing and verifying synchronization of secure communications between secure communications terminals (103, A, 109, B), and initiating (273, 275, 277) secure communication are used. <IMAGE> |
