Improved forward-secure digital signature scheme
Liu Sheng-quan · Journal of Computer Applications · 2008
The existing forward-secure digital signature schemes can not provide backward security for digital signatures.Improvement was made to the Abdalla-Reyzin's forward-secure signature scheme with backword-secure detection by embedding the one-way hash chain into the digital signature of the scheme.The improved scheme provides not only forward security but also backward security for digital signature.
