A concept of interoperable authentication framework for dynamic relationship in Identity Management

The Identity Management (IdM) is a technology for systematically managing an entity's identity. There exist several kinds of IdM technology and are complicated to present a method for intersection and integration among them. It is also difficult to provide a consistent level of security because of mutually different certification mechanisms and strengths even in case of using a same IdM technology. Although authentication technologies manage the important role in the security, the IdM technologies describe a correlation with the authentication technologies in the abstract and general level. They do not well present how to request the necessary authentication technique and how to be offered as any kind of authentication type. This paper presents a method that provides an integration of the IdM technologies through the common authentication framework. The framework is able to configure dynamic CoT (Circle of Trust) according to each authentication technology. It also offers a consistent experience to the users not limited to a specific CoT. If a user passes a specific authentication level, the user can be offered an important service from non-trusted CoT which has a different IdM technology. Namely, the proposed framework provides the CoTs to integrate with dynamic relationship in the Internet level.
