In order to replace the traditional voting system, This paper proposes voting protocols that satisfy a variety of security requirements. However, much room for improvements remains, regarding efficiency, participation of trusted authorities, prevention of vote buying and coercion, and formulation of admissible ballots. This paper surveys the security requirements, voting schemes and ballot formats of the current electronic voting system. It puts forward four main challenges faced with electronic voting protocols and introduces with detailed analysis several typical solutions, including visual cryptography, self-tallying election, vector-ballot voting and divisible voting.

Key words: Electronic voting, Visual cryptography, Self-tallying, Vector-ballot voting, Divisible voting

摘要：

电子选举是密码研究领域中一个非常有挑战性的问题，它满足广泛的安全要求，逐步取代传统的选举形式。现有的安全电子选举方案在计算效率、可信第3方的使用、防止买卖选票和胁迫投票，以及允许的选票形式等方面存在着改进的空间。该文在对电子选举方案的安全要求、协议模型和选票形式进行分析归纳的基础上，提出了电子选举研究面临的4个挑战，阐述了视觉密码选举、自计票选举、矢量选举和可分选举等最新的电子选举方案在这些方面获得的进展。
