An Improved Security and Trusting Model for Computational Grid

Free registration required

Executive Summary

Grid Computing in today's world is a boon for high speed computing. Grids are composed from intersection of clusters, which provide huge volume of computing power. An environment with broadly distributed resources is liable to various types of security attacks. To solve this problem, the authors use P-LEASEL algorithm, which provides secure multicast communications in grid environment. Kerberos is used for authentication. Trust computing is incorporated to perform trust evaluation for the nodes to prevent the entry of malicious nodes in a group.
