摘要
介绍了数字签名背景、签名体制的形式化描述以及两个特殊的数字签名方案。对如何用RSA实现盲签名和多重数字签名方案进行了研究,分析了两种具体方案实现的安全性。最后总结了这两种特殊数字签名实现过程中算法设计的优劣。
The background, the formal definition and some special form of digital signature are firstly introduced.The research of how to realize the blind signature and the multisignature with RSA signature scheme are carried out secondly. The virtue and shortcoming of the two realized special digital signature schemes and the research to be continued are lastly put forward.
