为了解决无证书部分盲签名中公共信息被窜改的问题,提出了一个新的无证书部分盲签名方案。新方案将公共信息和签名人的私钥绑定在一起,防止了窜改公共信息攻击,保证了签名的安全性。同时将方案与其他无证书部分盲签名比较,发现新方案在效率上更具有优势。
In order to deal with the problem of modifying the common information,this paper proposed a new certificateless partially blind signature scheme,the new scheme bound the common information with the private key.It could avoid the attack of modifying the common information,and could assure the security of partially blind signature.Moreover,compared with other certificateless partially blind signature schemes,the scheme was more efficient.
