A Forward-Secure Signature with Backward-Secure Detection
D.J. Guan, Dai-Rui Lin, Chih-I Wang · 2008
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.
