Research ArticleOpen accessIn the abstractMathematical Attacks on RSA CryptosystemImad K. Salah, Abdullah Darwish, Saleh OqeiliIn this paper some of the most common attacks against Rivest, Shamir, and Adleman (RSA) cryptosystem are presented. We describe the integer factoring attacks, attacks on the underlying mathematical function, as well as attacks that exploit details in implementations of the algorithm. Algorithms for each type of attacks are developed and analyzed by their complexity, memory requirements and area of … …Journal of Computer Science, Vol. 2, Issue 8 · 31 Aug 2006 · 8,420 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutonomic and Dependable Computing: Moving Towards a Model-Driven ApproachYuan S. Dai, Tom Marshall, Xiaohong GuanThe rapidly increasing complexity of computing systems is driving the movement towards autonomic systems that are capable of managing themselves without the need for human intervention. Without autonomic technologies, many conventional systems suffer reliability degradation and compromised security. Autonomic management techniques reverse this trend. This study describes the roles and functions of various autonomic components, and systematically reviews past and … …Journal of Computer Science, Vol. 2, Issue 6 · 30 Jun 2006 · 6,299 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Changing Pathology of NeuroAIDS Associated with Drug Abuse in the Era of HAARTE Bell Jeanne, C. Anthony Iain, Simmonds PeterCompliance with highly active antiretroviral therapy (HAART) arrests HIV induced immune collapse and reduces the prevalence of severe central nervous system (CNS) complications, including HIV associated dementia and encephalitis. However minor cognitive disorders remain common and recent autopsy studies have demonstrated the presence of subtle neuropathological abnormalities in HAART treated individuals, including persistent neuroinflammation and enhanced deposition in the brain … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 6,872 accessesView PDFCite
Research ArticleOpen accessIn the abstractHighly Efficient Elliptic Curve Crypto-Processor with Parallel GF(2m) Field MultipliersTurki F. Al-Somani, M. K. Ibrahim, Adnan GutubThis study presents a high performance GF(2m) Elliptic Curve Crypto-processor architecture. The proposed architecture exploits parallelism at the projective coordinate level to perform parallel field multiplications. In the proposed architecture, normal basis representation is used. Comparisons between the Projective, Jacobian and Mixed coordinate systems using sequential and parallel designs are presented. Results show that parallel designs using normal basis gives … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,874 accessesView PDFCite
Research ArticleOpen accessIn the abstractCommunication Architecture Synthesis for Multi-bus SoCAbdelkrim Zitouni, Sami Badrouchi, Rached TourkiIn the systems on chip (SoC) design, the synthesis of communication architecture constitutes the bottleneck which can affect the performances of the system. Various schemes and protocols can be necessary, just as various topologies of interconnection. To reduce the complexity of the communications refinement, we present in this study a model and a synthesis approach for multi-bus communication architecture containing … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,780 accessesView PDFCite
Research ArticleOpen accessIn the abstractQualitative Assessments of the Software Architectures of Configuration Management SystemsAbhay Kothari, A. K. Ramani, P. K. ChandeThe Configuration Management (CM) is a very important area of concentration in software development and maintenance processes. Quality parameters for Configuration Management Tools’ architectural designs require rigorous identification and measurement. Two methods for quantitative assessment of quality parameters of the software architectures are proposed. These methods are based upon modularization properties, like, cohesion type, coupling type, module complexity, module size … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,812 accessesView PDFCite
Research ArticleOpen accessIn the abstractTest of a Data Basis Oriented Object after Phase of ConceptionSoumia Layachi, M. T. LaskriThe concepts of the approach object introduce cause a lot of interest and make a large topic of survey of it. These concepts applied to the data base are going to allow us to master the complexity of the data base and facilitate us their reuse. If one considers the conception of a data basis oriented object a lot of … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,719 accessesView PDFCite
Research ArticleOpen accessIn the abstractFault-tolerant Distributed Systems with Diagnostics AlgorithmsOleg Viktorov, Afif MghawishTo provide consistent actions in distributed systems with faulty nodes the Byzantine agreement protocol (algorithm) is widely used. In case of using message exchange scheme without authentication the Byzantine agreement algorithm leads to agreement if the number of nodes doesn’t exceed 1/3 of the total number. The proposed algorithms based on diagnostics procedures are used to reach an agreement in … …Journal of Computer Science, Vol. 1, Issue 2 · 19 Oct 2005 · 4,840 accessesView PDFCite

Research ArticleOpen accessIn the abstractMusic Information Retrieval Schemes in Peer-to-Peer EnvironmentsChaokun Wang, Jianzhong Li, Shengfei ShiPeer-to-peer systems are useful tools for music applications. Existing peer-to-peer systems support the storing and sharing of music data, however they cannot effectively and efficiently support the content-based information retrieval and the cooperation of musicians. This study focuses on the methods of content-based music information retrieval in peer-to-peer environments. Four music information retrieval schemes are evaluated in detail on communication … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,551 accessesView PDFCite
