中文摘要：
针对目前指定验证者签名权可授权的问题,基于双线性对提出一种高效的基于身份不可授权的强指定验证者签名方案,采用密码学上安全性分析的方法,结果证明了新方案在保持了强指定验证者各种安全特性的条件下,其效率高于已有方案,更适合于在实际中应用。
英文摘要：
Faced with the delegatable problem of some existing designated verifier signatures,based on bilinear pairings,a new efficient identity-based non-delegatable strong designated verifier signature is proposed.Security analysis in cryptography is carried out to analyze the efficiency of the proposed scheme.Results show that the proposed scheme＇s efficiency is better than that of some existing ones under the condition of keeping all kinds of the security characteristics of strong designated verifier signature,so it is more propitious to applications in society.
