Research ArticleOpen accessIn the keywordsAnonymous and Non-Repudiation E-Payment ProtocolSattar J Aboud, Mohammed Ahmed AL-FayoumiThere are many proposals offer anonymous and non-repudiation e-payment protocols. But they have the drawbacks that the anonymity can be misused by fraudulent to perform a perfect crimes. Currently, the hot research concentrates on the accepting of e-payment protocols where the anonymity of the coins is cancelable via a trusted authority in the case of criminal entities. In the article … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,274 accessesView PDFCite
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
Research ArticleOpen accessIn the abstractBlind Decryption and Privacy ProtectionMohammed Al-Fayoumi, Sttar AboudBlind decryption is an efficient way of protecting customer’s privacy in online marketing over the Internet (i.e. Hiding information about which goods a user purchases from the vendor). In this study, the RSA based blind decryption is simply transposed from an identical protocol as the Chaum’s blind signature scheme and the blind decryption protocol for the Elgamal encryption scheme is … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,020 accessesView PDFCite
