摘要
分析基于身份的指定验证者签名方案的漏洞,指出任何人只要获取一个签名就可以验证以后所有的签名,并提出一个高效的基于身份的强指定验证者签名方案。该方案结合了单向认证密钥交换协议中的发送者前向安全性和已知密钥安全性等特点。与已知的基于身份的强指定验证者签名方案相比,该方案具有更强的安全性,且签名和验证算法更高效。
An ID-based designated verifier signature is analyzed,which shows that anyone who intercepts one signature can verify subsequence signatures without need of receiver＇s private key.Another ID-based designated verifier signature based on one-pass Authenticated Key Exchange（AKE） is presented.This scheme has strong security properties such as the known key security and the forward security that are derived from the one-pass AKE.Compared with the existing schemes,the scheme is much more efficient in sign and verify algorithms.
