The development of highly computerized society has generated a new important problem of "information security". One of effective schemes to cope with this problem is to introduce the cryptography, where the most important ploblem is how to share a common-key.In this project we have promoted the research on a new key management system for the super-large-scale cipher communication network. The basic ideas are the concept of identity-based cryptosystem, and a new creative idea to generate a clone key generation center of the original to decrease the load of key generation center. First, we have studied a new realization scheme of identity-based key sharing scheme which can be implemented easily and is secure even for the user's collusion attack. Then we have succeeded to generate a clone key generation center from time original. As a result the msil-type cipher communication in the super-large-scale communication network can be realized using the hierarchiically structured key generation center constructed by the clone key generation center.Finally, the possibility to use our key-management system in the real cipher communication network has been certified by implementing it on the PC cluster system.

高度信息化社会的发展产生了一个新的重要问题“信息安全”。科普这一问题的有效方案之一是引入密码学，其中最重要的问题是如何共享公共密钥，本课题致力于超大规模密码通信网络中新的密钥管理系统的研究。其基本思想是基于身份的密码体制的概念，并提出了一种新的创造性的思想，即生成一个原始密钥生成中心的克隆，以减少密钥生成中心的负载。首先，我们研究了一种新的基于身份的密钥共享实现方案，该方案易于实现，并且即使在用户合谋攻击下也是安全的。在此基础上，成功地从时间序列中生成了一个克隆密钥生成中心.最后，通过在PC机群系统上的实现，验证了该密钥管理系统在真实的密码通信网络中应用的可能性。
