IEC 62351-6 standard stipulates the use of digital signatures for ensuring integrity and authenticity in IEC 61850 Generic Object-Oriented Substation Events (GOOSE) message exchanges. Yet, it does not specify any method for ensuring confidentiality in GOOSE messages. With rapid growth of IEC 61850 from substation automation to power management domain, sensitive data that requires privacy is carried over GOOSE messages. In this letter, a novel method employing Authenticated Encryption with Associated Data (AEAD) algorithms is proposed to achieve both confidentiality and integrity of GOOSE messages. Further, lab tests are run to observe the timing performance and applicability of these algorithms to GOOSE messages with strict timing requirements.

实现 IEC 61850 GOOSE 消息保密性和完整性的方法

IEC 62351-6 标准规定使用数字签名来确保 IEC 61850 通用面向对象变电站事件 (GOOSE) 消息交换中的完整性和真实性。然而，它没有指定任何确保 GOOSE 消息机密性的方法。随着 IEC 61850 从变电站自动化到电力管理领域的快速发展，需要隐私的敏感数据通过 GOOSE 消息进行传输。在这封信中，提出了一种采用关联数据认证加密 (AEAD) 算法的新方法来实现 GOOSE 消息的机密性和完整性。此外，运行实验室测试以观察这些算法对具有严格时序要求的 GOOSE 消息的时序性能和适用性。
