摘要 对一种基于双线性对的新型门限代理签名方案进行了密码分析,发现该门限代理签名方案不能抵抗伪造攻击和公钥替换攻击。对该方案进行了改进,改进后的门限代理签名方案克服了原门限代理签名方案的安全隐患,并且保留了原门限代理签名方案的优点。 Through the cryptanalysis of a threshold proxy signature scheme based on bilinear pairings, it was found that the scheme couldn＇t resist forgery attack and public-key substitute attack. An improvement to mend the security leaks was proposed, which overcame the disadvantages and retained the merits of the original threshold proxy signature scheme.
