1) unforgeability
不可伪造性
1.
This paper demonstrates a concrete attack to show that the MV group signcryption scheme fails to have unforgeability.
利用MV群签密方案的安全漏洞构造具体的攻击:给定一个有效的密文,接收方中任何一个成员都可以伪装成发送方的成员产生其它有效的密文,从而证明MV群签密方案不满足不可伪造性。
2.
The existential unforgeability of the proposed scheme is equivalent to the computational Diffie-Hellman problem and its witness indistinguishableness is equivalent to the decis.
方案在随机问答器模型下证明是安全的,其不可伪造性等同于CDH(Computational D iffie-Hellman)问题;不可分辨性等同于DDH(Decisional D iffie-Hellman)问题;不可扮演性等同于离散对数问题。
3.
The security of the Li-Zhang s ID-based proxy blind signature scheme from bilinear pairings was analyzed, and it was found that this scheme did not possess the unforgeability property.
通过对Li-Zhang基于双线性映射的基于身份的代理盲签名方案的分析,指出该方案并不满足不可伪造性,原始签名人可以伪造一个有效的代理盲签名,代理签名人可以滥用代理签名权,同时当签名被用户泄露后,代理签名人能将自己在签名协议中的签名和签名的消息联系起来,这就是所谓的可追踪性。
2) unforgery
不可伪造性
1.
New scheme was proved to be unforgery under random oracle model.
在随机预言模型下,证明了新方案是基于计算D iffie-Hellm an问题无证书密文不可伪造性(CL-CUF)安全的。
3) strong unforgeability
强不可伪造性
1.
The proxy signature key is applied to ensure the property of strong unforgeability.
安全分析表明,改进方案使原方案具有强不可伪造性,有效提高了代理签名的安全性。
2.
Then a new anonymous proxy signature scheme without a trusted party is presented,which can keep the property of the strong unforgeability and does not have the redundant data in signature.
该方案具有强不可伪造性,且签名结果不含冗余数据。
3.
The analysis of the property of the strong unforgeability and the necessity of a secure channel is one of the important content for the security analysis of the LKK proxy signature scheme.
强不可伪造性和对安全信道依赖性的分析是对LKK代理签名方案安全性分析的重要内容之一。
5) strongly unforgeable signatures
强不可伪造签名
6) Existential unforgeable
存在不可伪造
