Grid computing is a new paradigm for accessing resources distributed across organizational boundaries using computer networks. It allows for new ways of accessing & using remote resources. This new paradigm demands for several new concepts concerning security, especially authentication and authorization. The most commonly used security framework for grid system is Grid Security Infrastructure. It makes use of proxy certificates & private keys as credentials for allowing single sign on and delegation of rights. Single Sign-On (SSO) are the desired feature of computational grids. Although there are several ways to implement single sign-on and delegation but in this paper, these have been implemented on Alchemi.NET based grid computing framework through X.509 proxy certificates.
