密钥管理是网络安全问题中的关键,具体处理密钥自产生到最终销毁的整个过程中的有关问题,包括系统的初始化,密钥的产生、存储、分配、更新、吊销、控制、销毁等。文章阐述了密钥管理的内涵与常用技术,尤其是密码系统中密钥生成与分配的具体技术,并进行了必要的分析和比较。
Key management is the core problem of network system security,which deals with the correlative problems from key being generated to ultimately destroyed,it includes system initialization,key generation,key encasement,key distribution,key storage,key renovation,key destruction,and etc.In order to protect the network,the suitable key management mechanism must be disposed,which prompts to produce and distribute dynamically,thus,it is necessary and important to study the key management problem of network,all of these have been discussed in this paper.
