Construction of Subliminal Channel in ID-based Signatures
Based on the bilinear pairings, by covering the subliminal message with a shared temporary key generated from the time stamp, an ID-based signature scheme with subliminal channel is proposed, which can be proved to be secure in random oracle under the hardness assumption of computing Diffie-Hellman problem (CDHP). According to the construction of the proposed scheme, it is found that it is easy to construct a subliminal channel in the ID-based signatures. Therefore, the existence of the subliminal channel in the ID-based signatures can also limit the applications of the ID-based signatures.
