摘要
文献[1]提出了一个无中央机构的电子投票协议,这种签名适合用在选举人在电子选举时找不到可信中心对选票进行认证的时候。但是,给出的一种攻击证明该协议是不安全的,不诚实的投票人可以控制整个选举的结果而不被其他人所察觉。针对上述缺点设计一个改进的新方案,主要引入一个不同底相同离散对数的知识证明来保证投票者给出正确的私钥。并对新方案的安全性进行了分析。最后对新方案的执行效率和还存在的缺陷进行分析。
An electronic voting protocol without authority is proposed by literature [1], which is suitable when voters can＇t find a eredible center to authenticate the vote the in e-voting. But the scheme is insure by given an attack＂ a dishonest voter can control the result of voting without realizing by others. An improved scheme is proposed to overcome the disadvantages, which ensure the voter to give out his correct private key by using two different bases and the same discrete logarithm proof of knowledge. Then we analyze the security of new scheme. At last, the efficiency and the shortcomings of the new scheme are analyzed.
