Abstract :
Security has been a major concern for grid computing systems owing to their dynamic nature, heterogenity, scalability and presence of multiple domains. Grid security has always been viewed as an authentication problem rather than an authorization issue. Accessing resources across a secure channel is essential in a grid scenario. In this paper, we present a cross domain role-based delegation and revocation model for grids with its implementation. Access control through delegation and revocation helps us to meet the dynamic access requirements prevalent in grids.
