Security analysis of two forward-secure blind signature schemes
Xiao Guo-zhen · Journal of Xidian University · 2010
Forward-secure blind signature schemes can provide important security guarantees: all secret keys and digital signatures before current key exposure will still be secure.We make a Security analysis of the recent two new forward-secure blind signature schemes respectively proposed by Hui-Feng Huang et al and Yali Liu et al.These schemes are totally broken by cryptanalysis on the key structure or hardness problem.It is proved that they are not forward-secure.
