| 摘 要： | 描述了一种基于公钥加密的新型Kerberos域间认证方案.鉴于以往Kerberos域间认证方案中域间存在密钥数量庞大和系统安全性不够强的问题,引入了中介KDC和公钥加密体制对Kerberos域间认证方案进行改进.改进方案中,中介KDC和与之相关的非中介KDC共享对方公钥.通过可行性、安全性分析可知,该方案使系统更安全,密钥的管理和维护更容易.

| Abstract: | 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. |
