A key establishment protocol includes the generation of a value of cryptographic function, typically a hash, of a session key and public information. This value is transferred between correspondents together with the information necessary to generate the session key. Provided the session key has not been compromised, the value of the cryptographic function will b e the same at each of the correspondents. The value of the cryptographic function cannot be compromised or modified without access to the session key .
