| 摘 要： | 椭圆曲线密码体制（ECC）以椭圆曲线离散对数问题的难解性为基础，相比其他密码体制，其安全性更高、操作数更短，针对该特点，设计基于ECC的自认证盲签密方案。该方案对签密消息进行盲化处理，非法用户在未知盲因子的情况下很难分析出明消息，可有效防止非法用户对消息进行抵赖、伪造和篡改，满足盲签密的正确性、匿名性、不可伪造性和不可跟踪性。

| Abstract: | Based on the analysis of proxy multi-signature, multi-proxy signature, multi-proxy multi-signature and blind signature schemes, novel broadcasting and sequential multi-proxy blind multi-signature schemes based on Elliptic Curve Cryptography(ECC) are proposed by combining multi-proxy multi-signature with blind signature. Security of the new schemes is analyzed. Cryptanalysis shows that they both satisfy security requirements of multi-proxy multi-signature scheme and non-trail and blindness for blind signature. |

| Keywords: | digital signature multi-proxy blind multi-signature Elliptic Curve Cryptography(ECC) non-trail |
