摘要
工业控制系统广泛应用于电力行业,成为维护电力系统安全、平稳运行的基础。为改进电力工业控制系统在电力设备信息安全技术上的不足,介绍了一种具有自主知识产权的配电自动化远方终端(RTU)的设计与实现方法。安全RTU采用自主可控的国产芯片作为核心处理器,通过外扩电能计量芯片提高采样精度,简化设计。基于国产加密算法的安全机制能实现数据在VPN隧道密文传输和用户认证访问。在实验室模拟工业现场测试表明该方法可以有效防止信息泄露以及木马病毒的攻击。
Industrial control system is widely used in power industry, which has become the base of maintaining power system running safely and steadily. To improve the deficiency of power industry control system in power equipment information security technology, this paper introduces a design and implementation method of distribution automation remote terminal(RTU) which is based on independent intellectual property rights. Secure RTU chooses a self-control homebred chip as the core processor, an energy measurement chip is extended to improve the acquisition accuracy and simplify the design. The security mechanism based on homebred encryption algorithm allows the cryptograph transfer in the VPN channel and credentials access. Test in the laboratory shows that this method can prevent information leakage and the Trojans virus.
