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.

高度计算机社会的发展产生了一个“信息安全”的新重要问题。解决此问题的有效计划之一是介绍密码学，其中最重要的拼图是如何共享一个共同的钥匙。在该项目中，我们促进了针对超大型密码密码通信网络的新关键管理系统的研究。基本思想是基于身份的密码系统的概念，也是一种新的创意，是生成原始的克隆密钥生成中心，以减少密钥生成中心的负载。首先，我们研究了一种基于身份的密钥共享方案的新实现方案，该方案可以轻松实现，即使对于用户的勾结攻击也是安全的。然后，我们已经成功地从时间开始生成了克隆密钥生成中心。结果，可以使用克隆密钥生成中心构建的层次结构的密钥生成中心来实现超大级通信网络中的MSIL-type密码通信。从本文中，可以通过在PC Cluster系统上实现我们的PCER-CIPHER通信网络中使用我们的密钥管理系统。
