Research ArticleOpen accessAll words, across the recordA Stringent Authorization using Principles and Policy for Grid ComputingA. R. Jayasudha, T. PurusothamanProblem statement: The current information security mechanisms are insufficient to address authorization issues. The access control models today are mostly static and they are not wellsuited for the service-oriented environments where information access is dynamic in nature. Traditional authorization security techniques do not directly address these concerns as they primarily use access control lists for authorization, where the user whose … …Journal of Computer Science, Vol. 7, Issue 8 · 8 Aug 2011 · 6,638 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTask Load Balancing Strategy for Grid ComputingB. Yagoubi, Y. SlimaniWorkload and resource management are two essential functions provided at the service level of the Grid software infrastructure. To improve the global throughput of these environments, effective and efficient load balancing algorithms are fundamentally important. Most strategies were developed in mind, assuming homogeneous set of resources linked with homogeneous and fast networks. However for computational Grids we must address main … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 7,609 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Secure Protocol Based on a Sedentary Agent for Mobile Agent EnvironmentsAbdelmorhit E. Rhazi, Samuel Pierre, Hanifa BouchenebThe main challenge when deploying mobile agent environments pertains to security issues concerning mobile agents and their executive platform. This paper proposes a secure protocol which protects mobile agents against attacks from malicious hosts in these environments. Protection is based on the perfect cooperation of a sedentary agent running inside a trusted third host. Results show that the protocol detects … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 6,881 accessesView PDFCite
