Abstract
The paper introduces a novel transactional authentication framework for distributed environments, built upon the established Kerberos protocol. This framework tackles the security vulnerabilities inherent in multi-client and server interactions during transactions, ensuring robust authentication, data integrity, and confidentiality. By utilizing the Key Distribution Center's (KDC) trusted third-party function in Kerberos, the framework provides clients with time-limited session tickets, eliminating the requirement for repeated authentication during a transaction. This novel strategy promotes a distributed system's transactional environment that is safer and more effective. Key Words: Kerberos, Key Distribution Center's (KDC), Ticket, Pre-Authentication, Token, Security Authentication, Authorization.
