摘要
数字签名用来保证原始数据完整性和有效性,一个数字签名方案包括数字签名生成算法和数字签名验证算法.简短地介绍了盲签名、代理签名的基本思想和基本性质,并给出如何通过非对称密码算法的思想来实现这些签名方案,提出并详细介绍了一种基于离散对数问题的有存根的(免责声明)代理盲签名方案,讨论了基于离散对数问题的密码学算法的可能攻击方法,在此基础上给出了协议实现时的一些有益的建议.
A digital signature is used to ensure completeness and effectiveness of some original data. A digital signature scheme consists of a signature generation algorithm and an associated verification algorithm. This paper provides a brief introduction to the basic ideas behind blind and proxy signatures, and shows how these signatures can be realized through reversible public- key encryption techniques, describes in detail a proxy blind signature scheme based on The Discrete Logarithm Problem. Finally, we discuss some techniques based on the intractability of the discrete logarithm problem. Based on above it shows some profit advise which agreement achieving.
