Designated Verifier Signature Scheme with High Security
Ting Wu · Jisuanji gongcheng · 2009
This paper analyzes the security of Designated Verifier Signature(DVS) scheme, and overcomes the problem of existing scheme that attacker can realize signature verification without knowing the private key of designated verifier by introducing secret information of signer.This scheme can insure the signature to be indistinguishable, resists signer to deny and private key generator to entrap.Compared with existing safety modes, this scheme has high security.
