基于SM2的无证书可截取签名方案
SM2-based Content Extraction Signature Scheme Without Certification
摘要
Abstract
With the SM2, a new certificateless content extraction signature scheme based on elliptic curves was proposed. The scheme satisfied the requirements of unforgeability and privacy of the content extraction signature and prevented the dishonest extractor from tampering with the content of signature. The scheme was proved safe in the random oracle model, which could effectively resist existentially un-forgeable under adaptive chosen-message attacks.The performance analysis showed that the scheme could improve the efficiency of the algorithm compared with the existing scheme by reducing the hash operations in the signing and verification process.关键词
