A progress report on subliminal-free channels
説明
Subliminal channels axe closely related to covert channels and are used to hide secret information. They abuse the communications resource. Subliminal channels can be introduced in many cryptographic systems, and exploit the inherent randomness of the systems. For example, secret information can be hidden in the randomness of the authenticators of an authentication system. Similarly secret information can be hidden in the randomness (of the prover or verifier) of both zero-knowledge proof systems and signature systems.
