[Sim84] introduced the concept of subliminal channel in the context of signature systems. [Des88b] presented a solution against subliminal channels and extended in [Des88a] the solution to abuse-free coin-flipping, abuse-free generation of public keys, and abuse-free zero-knowledge. In this paper we demonstrate that a whole family of systems (generalized Arthur-Merlin games) can be made abuse-free, avoiding the exhaustive approach of [Des88a]. We will hereto formalize the concept of abuse.
