Abstract

The emerging Grid infrastructure presents many challengesdue to its inherent heterogeneity, multi-domain characteristic,and highly dynamic nature. One critical challengeis providing authentication, authorization and accesscontrol guarantees. In this paper, we present the SESAMEdynamic context-aware access control mechanism for pervasiveGrid applications. SESAME complements currentauthorization mechanisms to dynamically grant and adaptpermissions to users based on their current context. The underlingdynamic role based access control (DRBAC) modelextends the classic role based access control (RBAC). Wealso present a prototype implementation of SESAME andDRBAC with the Discover computational collaboratory andan experimental evaluation of its overheads.
