Controlled access to confidential information and resources is a critical element in security systems. Role based access control (RBAC) has gained widespread usage in modern enterprise systems. Extensions have been proposed to RBAC for incorporating spatial constraints into such systems. Several solutions have been proposed for such models and much research has now been directed towards enforcing system policies. The thesis proposes a security framework for RBAC systems with spatial constraints based on identity based encryption. Integration of identity based encryption and with zero knowledge proof is proposed to provide authentication and information security. We also show how Near Field Communication can be used to establish the integrity of a user’s proof of location. We discuss the design choices made in the protocol and explain the protocol implementation. Simulation results in Java validate our model. Furthermore, security analysis has been done to show how our framework protects against well-known attacks.
