In the contemporary world, Internet based services undoubtedly plays a vital role in supporting business processes. Yet, these services suffer from poor authentication methods, leading to intensive attacks. To address this issue and to enhance the security, in this paper, a cutting edge tetrahedron (3D) based two-server Password Authenticated Key Exchange (PAKE) protocol using ElGamal and Diffie-Hellman...
Authentication remains as significant security challenge in hadoop environment. Hadoop does not strongly authenticate the client. As a result, data nodes can be accessed using block locations. This paper suggests the usage of the fundamental properties of a triangle and dual servers to improve the security level of hadoop clusters The password given by the user is interpreted and alienated into more...
Semantic web using personalization support to provide relevant search results for searcher. Ontology is an effective method for modelling digital collections and user contexts. User profiling is commonly employed nowadays to enhance usability as well as to support personalization, adaptivity and other user-centric features. This work aims at creating a user profile ontology that incorporates concepts...
Grid Computing refers to the combination of computer resources from multiple administrative domains to reach a common goal. Grids which are a form of distributed computing contains collection of resources that are available for an application to perform tasks. The resources in the grid are generally heterogeneous, geometrically dispersed and belong to different administrative domains. The important...
A Grid allows its constituent resources to be used in a coordinated fashion to deliver various qualities of service, relating for example to response time, throughput, availability, and security, and/or co-allocation of multiple resource types to meet complex user demands, so that the utility of the combined system is significantly greater than that of the sum of its parts. Security is a major concern...
