Abstract:
 	As wireless networks become more prevalent, a widening array 
 of computational resources becomes available to the mobile user. 
 Since not all users should have unrestricted access to these 
 resources, a method of access control must be devised.  In a 
 context-aware environment, context information can be used to 
 supplement more conventional password-based access control systems. 
 We believe the best way to achieve this is through the use of 
 Context-Aware Role-Based Access Control, a model in which permissions 
 are assigned to entities called roles, each principal is a member of 
 one or more roles, and a role's membership is determined using 
 context information.  We designed and implemented RDL 
 (Role-Definition Language), a simple, expressive and somewhat 
 extensible programming language to facilitate the description of 
 roles in terms of context information.
