摘　　要：适配器签名方案能够在区块链中提供很好的原子交换性质,并已在实践中得到广泛应用。以改进的安全RSA密码系统(ISRSAC)数字签名算法为基础构造了一个新的适配器签名方案。在证明所提方案满足预签名的正确性、不可伪造性、预签名的可适配性、证据的可提取性和签名方案的安全性后,将其与基于SM2数字签名算法的适配器签名方案、基于Schnorr的适配器签名方案和基于ECDSA的适配器签名方案在时间开销、主要计算量等方面进行对比分析。分析结果表明,所提方案在时间开销上与其他方案相差不多,但所提方案扩展了ISRSAC算法在当前环境中的应用场景,且ISRSAC算法和适配器签名技术的结合使适配器签名的选择更具灵活性,应用范围更广。The adapter signature scheme can provide good properties of atomic exchange in the block chain,and has been widely used in practice.A new adapter signature scheme was constructed based on a digital signature algorithm for improved security of RSA cryptosystem(ISRSAC).After proving that the proposed scheme satisfied the correctness of the pre-signature,unforgeability,adaptability of the pre-signature,extractability of the evidence and the security of the signature scheme,it was compared with the adapter signature scheme based on the SM2 digital signature algorithm,the Schnorr-based adapter signature scheme and the ECDSA-based adapter signature scheme.And these schemes were analyzed in terms of time overhead and main calculation amount.The analysis results show that the proposed scheme is similar to other schemes in terms of time overhead,but the proposed scheme expands the application scenarios of ISRSAC algorithm in the current environment,and through the combination of ISRSAC algorithm and adapter signature technology,the selection of adapter signature is more flexible and can have a wider range of applications.
