摘　　要：在现阶段的指定验证者签名中主要存在执行效率低、安全性不高等问题,因此设计出安全、高效的指定验证者签名方案具有重要意义.在借鉴现有方案的基础上引入基于身份的签名方案,提出了一个新的基于身份的指定验证者签名方案.对新方案的安全性给予分析和证明,同时给出了方案的计算量代价,结果表明新方案可以满足指定验证者签名的性质,同时克服了指定验证者签名中存在的可委托性缺陷.There were such kind of issues as low performance and imperfect security in the current designated-verifier signature. So it is important to design secure and efficient designated verifier signature schemes. The introduction of identity-based signature scheme, proposed a new ID based designated verifier signature scheme based on the advantages of the existing schemes, listed the interrelated algorithm of the scheme. Carried on security analyzed and has given the theorem and certification in secure aspect, gave the cost of calculating amount to the scheme. The results showed that the new signature scheme proposed had meet the specific nature of the designated verifier signature, overcome defects that may be delegated presenting in the designated verifier signature at the same time.
