Research ArticleOpen accessIn the abstractA New Partially Blind Signature Based on Factoring and Discrete LogarithmsN.M.F. Tahat, S.M.A. Shatnawi, E.S. IsmailPartially 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 … …Journal of Mathematics and Statistics, Vol. 4, Issue 2 · 30 Jun 2008 · 7,057 accessesView PDFCite
