CONTEXT-AWARE BASED INTEGRATED SECURITY SYSTEM FOR USER AUTHENTICATION AND ACCESS CONTROL IN UBIQUITOUS COMPUTING ENVIRONMENTS

摘要

A context aware integrated security system for user authentication and access control appropriate for ubiquitous computing environment is provided to manage all the context information appropriate for ubiquitous sensor network environment within a security management domain. A context aware integrated security system for user authentication and access control comprises a context aware security service manager, a context manager, and a security policy manager. The context aware security service manager manages policy, provides a security service and manages user authentication for the user authentication and the access control in a context aware system. The context manager, connected to the context aware security service manager, collects and manages the context needed for performing context-role based access control of the context aware security service manager. The security policy manager controls context aware security policy and manages a security policy database for managing the security policy of the context aware security service manager and the context manager.
