After being released by the Chinese government as a component of the Chinese public key crypto standard, the SM2 digital signature method has now evolved into an algorithm that is recognized as a standard on a global scale. In this paper, we propose an efficient and secure identity-based multisignature scheme based on the SM2 algorithm. The security of our suggested scheme is established in the random oracle model based on the Elliptic Curve Discrete Logarithm Problem (ECDLP). Our proposed scheme is practicable for real-world applications, as evidenced by security analysis and experimental evaluation.

摘要

After being released by the Chinese government as a component of the Chinese public key crypto standard, the SM2 digital signature method has now evolved into an algorithm that is recognized as a standard on a global scale. In this paper, we propose an efficient and secure identity-based multisignature scheme based on the SM2 algorithm. The security of our suggested scheme is established in the random oracle model based on the Elliptic Curve Discrete Logarithm Problem (ECDLP). Our proposed scheme is practicable for real-world applications, as evidenced by security analysis and experimental evaluation.
