Authentication Protocol Using Authorization Ticket in Mobile Network Service Environment

A ubiquitous network environment is a system where the user can access network services anytime, anywhere. Studies are continuously being conducted on wireless communication technology and mobile devices to establish such an environment. The company that provides such services, at a charge to users, should have an established system for authentication and authorization. This service is referred to as Authentication, Authorization and Accounting (AAA). Existing studies have promoted the authentication and efficiency of mobile devices. One scheme requires the mobile device to contact the home authentication server every time through the external authentication server. Another uses a relay server to provide authentication between them. Thus, this paper aims to determine the best scheme to use ticketing, where tickets are provided through a mobile device by completing authentication and authorization features. In addition, it can efficiently provide mobile verification processing.
