摘要
基于强(t,n)密钥绝缘的盲签名算法和哈希函数设计了一种安全实用的大规模选举协议。与现有的电子选举协议相比,该方案增强了签证机构签名私钥的安全性,其私钥每个阶段演化一次,而计票机构的验证公钥保持不变。投票人在不同的时段申请签名和进行投票,可以有效地抵御拒绝服务攻击。同时,利用单向哈希函数的连接构造选票,保证了选票的秘密性。
A secure and practical electronic voting protocol of large-scale general election is designed based on strong （t,n） key-insulated blind signature scheme and Hash function. The protocol enhances the security of the private key of administrator center. The private key is evolved every period and the public key is kept constant. Voters apply for signatures of the administrator and vote in different periods,which can resist DoS effectively. At the same time, the secret of ballot is guaranteed by the connection of one-way Hash function.
