结合ElGamal密码体制和RSA盲签名体制,设计了一个适合大规模选举的电子投票协议.在该协议中,选民将选票进行两次不同方法的盲化,既切断了选民与选票的联系,又真正保证了选票内容的安全性,满足了安全选举的基本要求.选票是由选举机构制定的电子选票,保证了无收据性,也提高了计票阶段的效率.该协议所需选民计算的参数较少,效率较高,适合于实际应用.
Based on ElGamal cryptosystem and RSA blind signature cryptosystem, an electronic voting protocol for large-scale elections is proposed. In the protocol votes blind ballots in two different methods so that the contact between votes and ballots is cut off, and the safety of the ballot content is ensured. On the other hand, because electronic-ballot draw up by election organization, no one can possess receipt and efficiency of counting ballot is raised. The scheme needs less correlation parameters of votes calculation and is high efficiency, and applicable in practice.
