Optical Code Authorization for Secure Device Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for configuring devices in security-relevant facilities lack effective methods to ensure that only authorized devices can configure other devices, potentially allowing unauthorized access.
Innovation Solution
A method where a first device displays a code, which is detected by a second device using an optical sensor, and then authenticated to a server. The server verifies the identity of the second device and authorizes the configuration of the first device based on the code representation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a code display method is implemented for device authorization, then security against unauthorized configuration is improved, but device complexity increases
Solution Approach 1:
A server acts as an intermediary between the first device (to be configured) and the second device (configuring device). The server receives the code from the second device, verifies its validity, and authorizes the configuration process. This mediator approach enhances security by centralizing authorization logic while keeping the individual devices relatively simple.
Solution Approach 2:
The first device generates and displays a code before the configuration process begins. This preliminary action allows the second device to obtain authorization in advance by reading the code and communicating with the server, ensuring that only authorized devices can proceed with configuration.
2Reliability
If optical code detection is used for authorization, then unauthorized access prevention is improved, but ease of operation deteriorates
Solution Approach 1:
The manual process of verifying device authorization is replaced with an optical detection system. The second device uses an optical sensor to automatically read the code displayed by the first device, eliminating the need for manual verification steps and reducing operational complexity despite enhanced security.
3Reliability
If server-based authentication is implemented, then configuration security is improved, but loss of time increases
Solution Approach 1:
The code is generated and displayed by the first device before the configuration process begins. This preliminary generation allows the second device to immediately read and submit the code to the server without delay, streamlining the authorization process while maintaining security.
Solution Approach 2:
The authorization process is expedited by using a pre-generated code that can be immediately read by the optical sensor and submitted to the server. This skips time-consuming steps such as manual verification or multi-step authentication protocols, reducing overall authorization time while maintaining security.

AI summary
Provided is a method for authorizing a configuring of a first device by a second device and a system for establishing a communication connection between a first device and a server over a network. The method comprises displaying, by the first device, an at least partially randomly generated first code, detecting, by the second device, the first code by means of an optical sensor, detecting, by the second device, a second code provided on a surface of the first device, authenticating the second device to a server, authenticating, by the server, an identity of the second device, sending, by the first device, a first representation of the codes to the server over a network, sending, by the second device, a second representation of the codes to the server, and authorizing, by the server, a configuring of the first device by the second device based on the representations.
