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.
