A Forward-Backward Secure Signature Scheme *
Dai-Rui Lin, Chih-I Wang, D.J. Guan · 2010
In this paper, we propose a method for enhancing the security of Abdalla and Reyzin’s forward secure signature scheme by introducing a backward-secure detection. In the proposed method, we employed the hash chain technique in the forward-secure signature scheme. With this, we can achieve not only forward security but also backward security for digital signatures.
