摘要
结合以太网无源光网络(EPON)的技术特点及配电网自动化对通信系统的要求,设计了一种基于EPON的配电网自动化通信系统;针对该系统存在的安全威胁,利用对称密码算法及询问—应答机制,同时遵循EPON系统多点控制协议(MPCP)子层基于询问的发现过程,提出了满足系统认证和加密需求的安全通信方案,并给出了该方案的实现方法。
Based on the characteristics of the Ethernet passive optical network （EPON） and the requirements of the distribution automation,this paper presents a novel communication system for distribution automation using EPON. And the security threats to the proposed architecture are analyzed. By utilizing the symmetric cryptographic techniques and challenge-response mechanism,a secure communication scheme with encryption and authentication functions is presented,which conforms to the polling-based multi-point control protocol discovery process. The implementation details of the scheme are also described.
