Context-aware security management system for pervasive computing environment

Abstract

This paper presents the context based authentication and authorization management system for security management in the pervasive computing environment, we explored security considerations of the pervasive computing environment. The proposed system adopts the context-role based access control model as access control model for enforcement of access control service based on various context informartion. We also studied the methodology to apply partial credential to user authentication. We introduce the authentication confidence index for applying the partial credential to authentication mechanisms. The authentication confidence index is also used for user-role activation in the access control service. This paper shows comparison between our system and related works, such as Cerberus and CASA. © Springer-Verlag Berlin Heidelberg 2007.
