【摘要】 密钥管理是处理密钥自产生到最终被销毁的整个过程所涉及的有关问题。本文论述了密钥管理系统各部分的设计与实现,它包括系统的初始化,密钥的生成、装入、分配、存储、更新、备份、恢复、保护、吊销和销毁等内容[1]。重点讨论了密钥的分配问题,包括成对用户通信和多用户通信情况,并根据Carlo Blundo[2]等建立的模型IKDC对EKI的分发进行了实例分析,得到了每一用户用来加密和解密的密钥集。更多还原

【Abstract】 key management is about the relative problem of key from coming into being to end. This paper gives the design and implementation of every part of the system. Initialization of the system and making, enclosing, distribution, storage, update of the key are given etc. Especially, the distribution including double users and multi-user communication are discussed. An example about distribute of EKI based on the model which was found by Carlo Blundo is given. And we get every user抯 key collection for encryption and decryption.更多还原
