*During the age of computer communications, it became possible to have real-time communications that was also:
#Hidden from external eavesdroppers.
#Protected from alternation with digital message authentication.

==Problem==
A shared secret is not really a secret any longer as either side gets to decide when to release the key and expose the communications, or allow fraudulent messages to be created, even long in the past.
