AI Technical Summary

Technical Problem

Existing low-voltage devices in power distribution networks are vulnerable to unauthorized access and manipulation due to unprotected communication protocols, lack of operating systems, and negligence in security procedures, posing risks to critical switching and control operations.

Method used

Implementing a dual authentication mechanism for communication-enabled low-voltage devices, involving initial authentication based on address information or encryption, followed by a second authentication using a transaction number (TAN) or mobile device interaction, to ensure secure execution of control commands.

Benefits of technology

Enhances security by preventing unauthorized access and manipulation, ensuring proper functioning of low-voltage devices, particularly those using unprotected protocols like Modbus, and integrating with existing secure communication methods for comprehensive network protection.

Abstract

Method for safely initiating an action by a communication-capable device (1) of low-voltage technology, which is designed to perform switching or control actions, by means of a remotely positioned control device (2), comprising - Implementation of a coupling between the communication-enabled device (1) and the control device (2), in which -- the control device (2) is designated as authorized to initiate switching or control actions by the communication-capable device (1) by means of messages, and -- a first authentication method and a second authentication method are defined and set up, - Receiving a message to perform an action by the communicating device (1), - Performing an initial authentication regarding the authorization to initiate an action through the message, using the first authentication procedure, - Performing a second authentication, different from the first, regarding the authorization to initiate an action through the message, using the second authentication method, and - The action will be performed by the communicating device (1) only if both authentications were successful.
