Book Part The Perception of Electronic Document Management Systems (Edms) as a Transformational Information and Communication Technology (Ict) for Public Institutions in Turkey(Taylor and Francis, 2013) Medeni, T.D.; Önaçan, M.B.K.; Kömürcü, R.; Dalbay, Ö.; Medeni, İ.T.; Sezgin, E.Conference Object Citation - Scopus: 2Improving Kerberos Security System for Cross-Realm Collaborative Interactions: an Innovative Example of Knowledge Technology for Evolving & Verifiable E-Society(2007) Zrelli, S.; Medeni, T.; Shinoda, Y.In this paper, we clarify the role of authentication systems as building blocks for Knowledge Technologies that constitutes the basis of an evolvable and trustworthy e-society. Such frameworks support the trustworthy cross-realm collaboration and user-friendly service provision through proper measures of authentication, privacy, integrity and secrecy of information. We define the requirements that such authentication systems must fulfill. Then, we present Kerberos as a candidate. We overview the basic operations and the cross-realm authentication model of Kerberos. Then we present the XKDCP extension as a solution for scalability and reliability issues in Kerberos cross-realm operations. With the proposed enhancements , we have achieved our goal on selecting an authentication system that matches the requirements for evolvable and verifiable e-society. © 2007 IEEE.
