Grid Computing: A solution to processing time and power issues

Abstract

Grid computing is a method of harnessing the power of many computers in a network to solve problems requiring a large number of processing cycles and involving huge amounts of data. The grid computing helps in exploiting underutilized resources, achieving parallel CPU capacity; provide virtual resources for collaboration and reliability. But, large-scale deployment of grids will occur when users can count on their security. On the grid, participation often takes place at the organizational rather than the individual level. Thus, expressing restrictive policies on a user-by-user basis often proves difficult. Grid security is a multidimensional problem. Organizations participating in grids must use appropriate policies to harden their Infrastructures while enabling interaction with outside resources. This paper will describe the reasons for using grid and analyze the security requirements of large-scale grid computing. We propose a security policy for grid systems that addresses requirements for single sign-on, interoperability with localpolicies, and describe security architecture and associated protocols.
