摘要
智能化变电站建设的稳步推进对变电站内光通信网络的安全性要求日益提高。为了解决该问题,首先对智能变电站环境下光网络所面临的通信安全挑战进行了分析,提出了一种面向智能化变电站业务的光网络的信令安全优化技术。该技术充分利用电力光网络现有的信令协议进行扩展加强,设计了一种轻量级的安全信令机制以建立面向电力业务的端到端可信连接。以智能化变电站通信业务作为典型应用场景,对站内光网络的安全信令交互进行仿真验证。仿真结果表明,本文所提出的机制有效提高了变电站通信业务与电力光网络交互的安全性,并有力保证了电力通信业务的连接成功率。
The communication security issue brought by smart substation is of great importance and should not be ignored in backbone optical networks. To solve this problem, firstly, the communication security challenges faced by optical networks in smart substation environment were analyzed, a signaling security optimization technique for optical networks for smart substation services was proposed. A so-called light-weighted security signaling scheme was designed to establish the end-to-end trusted connection. Under the environment of multi-domain communication services in smart substation, evaluation simulation for the signaling interaction was conducted. Simulation results show that the proposed approach can greatly enhance the security ability of multi-domain optical network with better performance in term of connection success rate.
