A New Forward-Secure Blind Signature Scheme
Hang Huan-hua · Journal of Wuhan University · 2011
The blind signature plays an important role in protecting the senders' privacy,and the forward-secure digital signature can effectively reduce the loss that aroused for the reason of secret keys exposure.At present,some forward-secure blind signature schemes have been proposed,but they are mostly incorrect or insecure.In this paper,based on Schnorr blind signature,we propose a new forward-secure blind signature scheme,and prove that the proposed scheme has strong blindness,forward security and unforgeability in the random oracle model.The efficiency analysis is also discussed.
