    Abstract: The present invention relates to a method for analysing a log (10) of a device or a plurality of devices of a first entity (1), the method comprising:generating an encrypted log (11) by encrypting said log (10) on at least one device of the first entity (1); generating at least an encrypted query (16) by encrypting said query (16) on at least one device for analysing the log (10); transferring said encrypted log (11) and said encrypted query (16) from said first entity (1) to a second entity (2); analysing said encrypted log (11) on said second entity (2) by using the encrypted query (16) and generating (20) an encrypted analysis result (21); transferring said encrypted analysis result (21) from said second entity (2) to said first entity (1); and decrypting (22) said encrypted analysis result (21) on said first entity (1), wherein said decrypted analysis result (23) can be verified by said first entity (1).

    Abstract: The present invention is concerned with a stability supervision or monitoring of a communication system of an industrial Process Control (PC) system, by measuring the communication load and comparing the latter to a previously established base load. The measured communication load is represented by a plurality of updated, or present, echo delay measurements for communication paths between a supervising Intelligent Electronic Device IED and end-IEDs of the communication system. The echo delays are established by sending, by the supervising IED, echo poll messages to the end-IEDs, and by receiving an echo from the end-IEDs. If a difference between measured and baseline echo delays exceeds a predetermined threshold, an overload status is signalled to an operator. Hence, a refined dynamic communication network status, beyond a mere binary good/bad indication, is obtained without additional hardware and excessive dedicated communication load.

    Abstract translation: 本发明涉及对工业过程控制(PC)系统的通信系统的稳定性监视或监视,通过测量通信负载并将其与先前建立的基本负载进行比较。 所测量的通信负载由对监控智能电子设备IED和通信系统的终端IED之间的通信路径的多个更新或存在的回波延迟测量值表示。 回波延迟通过发送IED监听回波轮询消息到终端IED,并通过接收来自终端IED的回声来建立。 如果测量和基线回波延迟之间的差异超过预定阈值,则向操作员发信号通知过载状态。 因此,在没有额外的硬件和过多的专用通信负载的情况下,获得超出仅二进制好/坏指示的精细动态通信网络状态。

    Abstract: The present invention discloses a method of transmitting time-critical messages in an OSI layer 2 network tunnel from an IED in a first substation to an 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 IED model in the second substation using the translated values of the message parameters, to impersonate the IED of the first substation, c) translating the message parameters according to the translation table, d) forwarding the time-critical messages from the IED in the first substation to the WAN, and e) receiving the time-critical messages by the IED of the second substation from the WAN.
