N2 - In this paper, we consider the subliminal channel, hidden in an identification scheme, for signature transfer. We point out that the direct parallelization of the Fiat-Shamir identification scheme has a subliminal channel for the transmission of the digital signature, which does not exist in the serial (zero-knowledge) version. We apply this subliminal channel to a multi-verifier interactive protocol and propose a distributed verification signature that cannot be verified without all verifiers' corporation. Our proposed protocol is the first implementation of the distributed verification signature without secure channels, and the basic idea of our construction suggests the novel primitive with which a signature transfer secure against adversary can be constructed using only one-way function (without trapdoor).
