Towards an Enhanced Authentication Framework for E-government Services: the Greek Case

It is widely accepted that electronic Government environments have caused a complete transformation of the way individuals, businesses and governmental agencies interact with central government. However, the acceptance and success of e-Government services largely depend on the level of trust and confidence developed by the users to the provided services and the overall system security. Thus the employment of the appropriate authentication framework is a crucial factor. This paper focuses on the way to determine the appropriate trust level of an electronic service. Specifically, it provides guidelines according to the data required for a transaction, as well as to the available authentication and registration mechanisms. Moreover, a Single SignOn architecture is proposed, supporting a uniform authentication procedure that depends on the level of trust required by the service. In the aforementioned research work specific requirements and limitations for Greece have been taken into account.
