Abstract

An integrated security system which seamlessly assimilates with current generation logical security systems. The integrated security system incorporates a security controller having standard network interface capabilities including IEEE 802.x and takes advantage of the convenience and security offered by smart cards and related devices for both physical and logical security purposes. The invention is based on standard remote authentication dial-in service (RADIUS) protocols or TCP/IP using SSL, TLS, PCT or IPsec and stores a shared secret required by the secure communication protocols in a secure access module coupled to the security controller. The security controller is intended to be a networked client or embedded intelligent device controlled remotely by to an authentication server. In another embodiment of the invention one or more life cycle management transactions are performed with the secure access module. These transactions allow for the updating, replacement, deletion and creation of critical security parameters, cryptographic keys, user data and applications used by the secure access module and/or security token. In another embodiment of the invention a security access module associated with the security controller locally performs local authentication transactions which are recorded in a local access list used to update a master access list maintained by the authentication server.
