Authenticated Remote Reset for Networked Control Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for resetting devices, especially in networked systems, often require direct contact and lack secure authentication, leading to potential unauthorized or accidental resets.
Innovation Solution
A method involving a device transmitting an error signal to a control unit, receiving an acknowledgment signal, and then sending a request signal, which is authenticated using a shared password to trigger a reset mechanism, ensuring secure and remote resetting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct contact with the device is required for resetting, then the reset operation is simple and direct, but it is inconvenient for users and does not support remote operation
Solution Approach 1:
The patent introduces a control unit as an intermediary between the user and the device. The control unit receives reset requests, generates authenticated response signals, and transmits them to the device. This mediator enables remote resetting operations while maintaining security through password verification, resolving the contradiction between operational convenience and system complexity.
2Reliability
If reset is performed without authentication, then the reset operation is fast and simple, but unauthorized or accidental resets may occur
Solution Approach 1:
The patent implements preliminary authentication before executing the reset operation. The control unit verifies the password in advance by comparing it with the stored password before generating the response signal. This preliminary verification ensures that only authorized users can reset the device, preventing unauthorized or accidental resets while maintaining a relatively simple overall structure.

AI summary
The invention relates to a method for resetting a device (2). The device (2) transmits an error signal (99) to a control unit (1). The control unit (1) outputs an acknowledgement signal (100). In response, the device (2) outputs a query signal (101). On the basis of the received query signal (101) and a password, a response signal (102) is generated by the control unit (1). On the basis of the response signal (102), information of the query signal (101) and a password, the device generates a comparison result on the basis of which a reset mechanism in the device (2) is triggered. The invention further relates to a device (2) and a control unit (1).
