Abstract

This paper implements Multiple User Authentication System to which the system authenticating with password only has been upgraded. The 4-staged authentication including user ID, password, smart card and access control information, etc. is used at the suggested Multiple User Authentication System. The user authentication system that this paper suggests has been developed based on SecuROS/FreeBSD with the function of access control added to FreeBSD kernel. It provides both the function to limit access range to the system to each user and the function to check that when inputting important information the demand is the one of the system thus, the reliability becomes increased. In the SecuROS/FreeBSD system, MAC and RBAC are being used. So, in the case of users accessing to the system, the information about the policies of MAC and RBAC to which users would access is used in the authentication. At the time, the access to system is permitted only when the access control information that users demanded satisfies all the access control rules which have been defined in the system.
