Analysis of Authentication Systems for Future Internet Service Environments

In the current Internet environment, there may exist a number of independently-operating authentication systems even within a single organization, according to the service types and service providing entities. Current silo-style isolated authentication system model has revealed critical problems in the aspects of usability, cost-effectiveness, extensibility and flexibility, and privacy protection. Recently, several next generation authentication systems have been actively developed by leading industrial and standardization institutions. This paper firstly analyzes the problems of current Internet authentication system environments. And then, the underlying idea, operating procedures, and pros and cons of the newly developed next generation authentication systems are analyzed so as to provide the selection guidelines for the new authentication systems and drive further development directions for future Internet authentication systems.
