A New Partially Blind Signature Based on Factoring and Discrete Logarithms
Journal of Mathematics and Statistics
Partially blind signatures played an important role in many electronic commerce applications. Many existing partially blind signature scheme based on a single hard problem but not secure. In this study, we propose a secure partially blind signature scheme based on factoring and discrete logarithms and show that the proposed scheme satisfies the partial blindness, randomization, unlinkability and unforgeability properties. We also analyse the computation cost of the proposed scheme.doi:10.3844/jmssp.2008.124.129 fatcat:rwwrykawkbbczlnjkrstknnu6y
