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 PDF Cite

Research ArticleOpen accessIn the abstractDigital Identities and the Promise of the Technology Trio: PKI, Smart Cards, and BiometricsA. M. Al-Khouri, J. BalThis article looks at one of the evolving crimes of the digital age; identity theft. It argues and explains that if three key technologies were implemented together namely biometrics, smart cards, and PKI, then they can deliver a robust and trusted identification and authentication infrastructure. The article concludes that such infrastructure may provide the foundation for e-government and e-commerce initiatives … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,783 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGenetic Algorithm and Tabu Search Attack on the Mono-Alphabetic Substitution Cipher in Adhoc NetworksA. K. Verma, Mayank Dave, R. C. JoshiWith exponential growth of networked system and application such as e-Commerce, the demand for effective Internet security is increasing. Cryptology is the science and study of systems for secret communication. In consists of two complementary fields of study: cryptography and cryptanalysis. This study presents a cryptanalysis method based on Genetic Algorithm and Tabu Search to break a Mono-Alphabetic Substitution Cipher … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 7,254 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAdaptive Update Policy for Proactive Management of Deadline Miss Ratio and Data Freshness in Real-Time Database ModelsSanjay Tanwani, Ashwani K. RamaniImportant applications, like e-commerce, online stock trading, traffic control demand real-time data services. Conventional database perform poor at these applications. A database for real-time data services has to support timing constraints and temporal consistency in addition to supporting characteristics of a conventional database system. In other words, it is desirable to execute transactions within its deadline using updated data reflecting … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,207 accessesView PDF Cite

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 PDF Cite

Research ArticleOpen accessIn the abstractA Secure Database Encryption SchemeZongkai Yang, Samba Sesay, Jingwen Chen, Du XuThe need to protect database, would be an every growing one especially so in this age of e-commerce. Many conventional database security systems are bugged with holes that can be used by attackers to penetrate the database. No matter what degree of security is put in place, sensitive data in database are still vulnerable to attack. To avoid the risk … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,348 accessesView PDF Cite
