| 摘 要： | 0 IntroductionIn 1996 ,Jakobsson, Sako and Impagliazzo introduced anew pri mitive called designated verifier proofs[1]. Suchproofs enable a prover Signy to designate who will be con-vinced by a proof .Furthermore,Jakobsson,Sako and Impa-gliazzo proposed a designated verifier signature. Designatedverifier signatures provide authentication of a message, with-out having the non-repudiation property of traditional signa-tures . They convince one-and only one-specified recipient thatthey are va…

| Abstract: | In a strong designated verifier proxy signature scheme, a proxy signer can generate proxy signature on behalf of an original signer, but only the designated verifier can verify the validity of the proxy signature. In this paper, we first define the security requirements for strong designated verifier proxy signature schemes. And then we construct an identity-based strong designated verifier proxy signature scheme. We argue that the proposed scheme satisfies all of the security requirements. |
