基于SM9的周期性可否认环签密方案的设计
Design of periodic deniable ring signcryption scheme based on SM9
摘要
Abstract
To address the conflict between privacy protection and responsibility tracing in traditional cryptographic schemes,a periodic deniable ring signcryption scheme based on SM9 was proposed.This scheme combined the SM9 identity-based cryptographic algorithm with deniable ring signature technology,and introduced a periodic mechanism to enhance the privacy protection of the signcryptors and the deniability of non-signcryptors.It ensured that the sign-cryptor's responsibility could be traced within a specific time period,while further protecting the signcryptor's privacy once the litigation period expires.The design not only guaranteed data integrity and security theoretically but also im-proved system efficiency through optimization.Analysis results indicate that the proposed scheme has advantages in pri-vacy protection,security,and computational overhead,making it suitable for high-privacy demand scenarios such as elec-tronic voting,financial transactions,and government confidential communications.关键词
