Title: A Strong Forward Security Digital Signature Scheme Based on RSA
Abstract: Strong forward-secrecy digital signature can prevent the loss of leakage of signature keys and minimize losses.In actual exploit code,attackers could easily conjecture the current time segment before and after signature private keys in accordance with current signature keys.In view of this hidden danger,a digital signature scheme based on the RSA is introduced.The scheme supposes that each signature user has own public and private keys,when public keys fixed,it sets a specific evolutionary algorithm of private keys,and adding disturb factors to increase the confusion of message's group signature.The attackers could also not generate a forged signature of previous time periods and after a communication timestamp is added,even the key-exposure is on the work.This evolutionary algorithm satisfies in forward and backward security and so does the signature scheme.
