"Improving Kerberos security system for cross-realm collaborative interactions: An innovative example of knowledge technology for evolving & verifiable E-society", 2007 IEEE International Conference on Research, Innovation and Vision for the Future, RIVF 2007, pp. 211-219.14244069439781424406944http://hdl.handle.net/20.500.12416/6260In 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.eninfo:eu-repo/semantics/closedAccessConference Object21121910.1109/RIVF.2007.369159
