Abstract :
In this paper, we propose a method to enhance the security of Abdalla and Reyzin ´s forward-secure signature scheme, by producing a backward-secure detection. In the proposed scheme, we embedded the hash-chain into the forward-secure signature scheme. It achieves not only forward-security but also backward-security for the digital signature.
