Jing Zhang · Microelectronics & Computer · 2008
In this paper,a novel Kerberos cross-realm authentication scheme based on public key encryption is presented.In order to solve the problems of enormous keys in Kerberos cross-realm authentication and the low security,this paper introduces the intermediary KDC and public key encryption to improve the Kerberos cross-realm authentication system.In this improved scheme both the intermediary KDC and the related common KDC share each other's public key.Through the analysis of feasibility and security,this scheme makes the system more secure,and the key management and maintenance becomes easier.
