摘　　要：由M.Thangaval等人在2018年提出的ISRSAC是通过增加因式分解的复杂性同时引入随机值对RSA算法的安全性进行的改进。本文基于ISRSAC算法设计了按序代理多重签名以及广播代理多重签名,然后对两种签名算法进行了安全性分析,结果表明其在确保安全性的同时满足代理多重签名的性质,而签名的方式也可以按照一定顺序或者不分前后顺序来选择,这使得两类签名方案有着较为广泛的应用前景。The ISRSAC proposed by M.Thangaval et al in 2018 improves the security of the RSA algorithm by increasing the complexity of factorization as well as introducing random values.In this paper,a sequential proxy multi-signature and a broadcast proxy multi-signature are designed based on the ISRSAC algorithm.Then,a security analysis of the two signature algorithms is carried out.Analysis results show that the two signature algorithms satisfy the characteristics of proxy multi-signature while ensuring the security,and the signature mode could be selected in a certain order or regardless of the order.The two signature schemes have wide application prospects.
