一种基于可信计算技术的电子投票方案

Electronic Voting Scheme Based on Trusted Computing Technology

在现有的电子投票方案中,要求满足以下前提:投票人所使用的客户端是安全的,投票人与管理者之间存在匿名的或秘密的通信信道,但这2点通常难以成立。为此,提出一种基于可信计算技术的电子投票方案,该方案利用可信计算技术保障客户端安全性,减少匿名信道或秘密信道的使用,提高电子选举的实用性,并且满足投票系统机密性、无收据性、公开可校验性等安全属性。分析结果表明,与同类方案相比,该方案的通信量较低,投票效率较好。

In current electronic voting schemes, there are the following preconditions that must be met, the clients that using by voters are secure, and the anonymous or secret communication channels are existent between the voters and administers. Therefore, a new scheme based on trusted computing technology is proposed, which can protect the clients, decrease the use of anonymous or secret communication channels, promote the practicability of the electronic voting system, meet the demands of security attributes such as confidentiality, receipt-free, open verification, etc. Analysis result shows that compared with similar schemes, this scheme has lower communication traffic and better voting efficiency.
