面向电子投票的SM2门限环签名方案
A SM2 threshold ring signature scheme for electronic voting
摘要
Abstract
Electronic voting has been widely used thanks to its efficient and convenient characteristics.How to ensure the authenticity of the voting results,protect the privacy of the voter's identity as well as improve the practicality of the voting system become the keys to design the electronic voting system.In this regard,a SM2 threshold ring signature scheme for electronic voting is proposed.It uses the threshold ring signature technology to ensure the authenticity of the voting results by allowing some members of a group of users to jointly generate signatures,and to achieve the privacy protection of the identity of the signer.The SM2 digital signature algorithm is used to ensure that the core cryptographic algorithm is au-tonomous and controllable while improving the overall efficiency of the scheme.Security analysis shows that the scheme guarantees the anonymity and non-forgeability.Efficiency analysis shows that the effi-ciency advantage of the scheme is significant compared to the existing schemes.The electronic voting pro-tocol using this scheme is efficient and practical while ensuring security.关键词
