保密电子投票是目前信息化时代广为使用的选举投票方案,可以提高选举的安全性、可靠性和公正性,以及增加选民的参与度.虽然保密电子投票方案具有许多潜在优点,如提高投票效率和方便性,但也面临着一些挑战,如信息安全问题、技术难题、隐私保护问题以及系统的信任度问题等.本研究针对这些问题,结合门限公开秘密体制(Number Theory Research Unit,NTRU)加密算法、向量编码方法,提出了一种基于安全多方计算的高效保密电子投票方案.为验证所提出协议的安全性,采用模拟范例方法进行了安全性证明.通过理论分析和实验仿真展示了本文提出方案的高效性,本方案具有实用价值,为解决电子投票过程中隐私保护问题提供了可行且高效的解决方案.
An Efficient and Secure Electronic Voting Scheme Based on Secure Multi-party Computing
Secrecy e-voting is a widely used election voting scheme in the current information technology era, which can improve the security, reliability and fairness of elections, as well as increase voter participation. Although secrecy e-voting scheme has many potential advantages, such as improved voting efficiency and convenience, it also faces some challenges, such as information security issues, technical difficulties, privacy protection issues, and trustworthiness of the system. In this study, an efficient and confidential e-voting scheme based on secure multi-party computation is proposed to address these issues by combining the threshold Number Theory Research Unit( NTRU) encryption algorithm and vector coding method. In order to verify the security of the proposed protocol, a simulation paradigm approach is used for security proof. The theoretical analysis and experimental simulation demonstrate the efficiency of the proposed scheme, and the protocol has practical value and provides a feasible and efficient solution to the problem of privacy protection in the e-voting process.
