摘    要:目前,前向安全签名体制在密码技术研究中备受关注并获得了深入的研究.过去提出的大多数方案中密钥更新与总时间段T指数或者对数相关.在T相对较大时,这无疑对算法的执行效率造成很大的影响.该文提出了一个新的基于强RSA假定的前向安全数字签名方案,该方案存储空间需求和算法执行效率均独立于总时间段T,并且通过引入预计算,本方案具有效率高,实用性好的特点.

关 键 词:前向安全  数字签名  强RSA假定

Forward-secure Signature Scheme Based on Strong RSA Assumption

Abstract:Recently, forward security has received a significant attention and has been extensively researched in the cryptographic community. Most methods which was proposed need exponent or log to time periods T in secret key updating phrase. When T is a large number, the executing efficiency will be affected deeply. In this paper, a new forward-secure signature based on strong RSA assumption is proposed. In which, both storage requirements and executing times are independent of time periods T. And using pre-computing, the protocol is quite more efficient.
Keywords:Forward-secure  Digital signature  Strong RSA assumption
