Identity-based strong designated verifier signature schemes
基于身份的强指定验证人签名方案*

We should specify a verifier in some circumstances.Using identity-based cryptography,this paper proposed a strong designated verifier signature and a strong designated verifier multi-proxy signature.It also analyzed the proposed schemes.The proposed strong designated verifier signature scheme was lower than Kang et al.'s scheme in the signing cost and verifying cost.The proposed strong designated verifier multi-proxy signature scheme could delegate n proxy signers.Thus it could prevent proxy signers abusing...
