工业网络中IBC体制密钥管理的研究与实现

Research and Implementation of IBC System Key Management in Industrial Networks

针对我国制定的IBC密码标准SM9在工业网络中的应用,建立了一套工业网络通信安全密钥管理系统。根据SM9中的密钥生成、密钥交换和信息加密传输、通信双方身份认证等流程规范,结合工业网络环境,设计并实现了工控设备密钥的全生命周期管理过程,形成了设备密钥的管理中心,实现了工业设备密钥全生命周期的安全管理,有效保障了SM9在工业网络应用中的密钥安全。给出的应用案例,可以为各企业密钥全周期管理提供借鉴。

Aiming at the application of IBC cryptographic standard SM9 in industrial network,a set of industrial network communication security key management system is established.According to the process specifications of key generation,key exchange and information encryption transmission,and identity authentication of both sides of communication in SM9,combined with the industrial network environment,the full life cycle management process of industrial control equipment keys is designed and implemented,the management center of equipment keys is formed,and the security management of the full life cycle of industrial equipment keys is realized,which effectively ensures the key security of SM9 in the applications of industrial network.An application case is given,which can provide reference for the full cycle key management of enterprises.
