Full Title or Meme
In Secret Key Cryptography two parties that wish to communicate have some method for creating pre-shared secrets which can be used to hide subsequent communications from others.
Context
- At least since the time of Julius Cesar there have been methods know to hide messages from prying eyes.
- 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.
