电子选举中的安全协议(英文)

Cryptographic Protocols for Electronic Voting

随着因特网上出现的一些小范围的电子选举,电子选举开始引起人们的关注.而电子选举中的关键技术之一是电子选举协议的设计,特别是在多种投票方式下大规模电子选举协议的安全性问题.讨论了优秀的电子投票系统应该具备的特点,及如何通过密码协议来实现这些特点;对电子选举协议提出了新的分类方法,并考察了其优缺点;并对已有的许多电子选举协议进行了分类整理,有助于人们更好地理解这一领域内所面临的挑战和问题;同时对电子选举系统的设计也给出了一些建议.

Electronic Voting has begun to move into the mainstream, with small online votes taking place on the Internet. Electronic Voting investigates how to conduct large-scale electronic Voting securely including various modes of voting. In this paper we will discuss the characteristics of a good Electronic Voting system and explore cryptographic Protocols that can be used to build actual implementations with these characteristics. We mainly study the Electronic Voting protocols as opposed to the Electronic Voting systems. We propose some new taxonomy of the security protocols proposed for Electronic Voting procedures and examine their advantages and shortcomings. The goal of the paper is to impose some order into the multitude of Electronic Voting mechanisms that would lead to a better understanding of challenges in the Electronic Voting field. In the end, we give some advices on Electronic Voting system design.
