Strong forward-secure digital signature scheme
Liu Sheng-quan · Computer Engineering and Applications Journal · 2008
Based on Abdalla-Reyzin’s forward-secure signature scheme,a strong forward secure signature scheme is proposed by introducing the mechanism of one-way hash chain into the digital signature of the scheme.Even if the malicious attacker can intrude the system at period i,it can not forge any signatures in the past and future periods.The security of our scheme relies on difficulty of solving square root problem on Z_N and one-way property of hash functions
