Abstract: The present invention discloses a method of transmitting time-critical messages in an OSI layer 2 network tunnel from a first TED in a first substation to a second IED in a second substation over a WAN, wherein each of the first and second substation comprises an edge IED and is associated with a substation LAN, wherein each of the time-critical messages comprises message parameters. The method comprises the steps of: a) creating a translation table comprising corresponding values of the message parameters, between the LANs and the WAN, b) defining a virtual FED in the second substation using the translated values of the message parameters, to impersonate the first IED, c) translating the message parameters according to the translation table, by the edge IED of the first and second substation, d) forwarding the time-critical messages from the first IED in the first substation to the WAN, and e) receiving the time-critical messages by the second IED in the second substation from the WAN.

Abstract translation: 本发明公开了一种在OSI第2层网络隧道中从第一变电站中的第一TED向广域网中的第二变电站中的第二IED发送时间关键消息的方法，其中第一和第二变电站中的每一个包括边缘 IED并且与变电站LAN相关联，其中每个时间关键消息包括消息参数。 该方法包括以下步骤：a）创建包括LAN和WAN之间的消息参数对应值的转换表，b）使用消息参数的转换值在第二变电站中定义虚拟FED，以假冒 第一IED，c）根据第一和第二变电站的边缘IED根据转换表翻译消息参数，d）将时间关键消息从第一变电站中的第一IED转发到WAN，以及e）接收 来自WAN的第二个变电站中的第二个IED的时间关键消息。

Abstract: A method can be used to analyze a log of a device or a plurality of devices of a first entity. The method includes generating an encrypted log by encrypting the log at the first entity, generating an encrypted query by encrypting a query at the first entity, transferring the encrypted log and the encrypted query from the first entity to a second entity, analyzing the encrypted log on the second entity by using the encrypted query, generating an encrypted analysis result at the second entity, transferring the encrypted analysis result from the second entity to the first entity, decrypting the encrypted analysis result on the first entity, and verifying the decrypted analysis result at the first entity.
