基于SM2的无证书可截取签名方案
|
摘要
结合国密算法SM2,提出一种新的基于椭圆曲线的无证书可截取签名方案.该方案满足可截取签名的不可伪造性和隐私性,并可防止不诚实的截取者对签名内容私自进行篡改.在随机预言模型下证明了该方案的安全性,能够有效抵抗适应性选择消息下的伪造攻击.性能分析表明,该方案通过减少签名验签过程中哈希运算的次数使算法效率得到提升.
With the SM2,a new certificateless content extraction signature scheme based on elliptic curves was proposed. The scheme satisfied the requirements of unforgeability and privacy of the content extraction signature and prevented the dishonest extractor from tampering with the content of signature.The scheme was proved safe in the random oracle model,which could effectively resist existentially unforgeable under adaptive chosen-message attacks.The performance analysis showed that the scheme could improve the efficiency of the algorithm compared with the existing scheme by reducing the hash operations in the signing and verification process.
