Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial control systems face security vulnerabilities due to unsecured edge devices, such as surveillance cameras, which can be exploited by malicious actors for unauthorized access or malware introduction, compromising the integrity of the system.
Innovation Solution
Implementing image capture devices with integrated image sensors, signal processors, and controllers that establish encrypted tunnels and perform authentication sequences using security credentials, ensuring secure data transmission and reception within the industrial control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If image capture devices are integrated into industrial control systems, then monitoring and surveillance capabilities are improved, but security vulnerabilities increase due to unsecured edge devices
Solution Approach 1:
The patent introduces security credentials as an intermediary mechanism between the image capture device and the industrial control system. These credentials act as a mediator that enables secure authentication and authorization, allowing the device to be integrated into the system without exposing security vulnerabilities. The security credentials verify the identity and permissions of the device, preventing unauthorized access while maintaining monitoring capabilities.
2Reliability
If security credentials and authentication sequences are implemented in image capture devices, then system security is improved, but device complexity increases
Solution Approach 1:
The patent implements security credentials and authentication sequences as preliminary actions that are established before the image capture device operates within the industrial control system. The security credentials are pre-configured in the device, and authentication sequences are performed during initial connection or before critical operations. This approach ensures security is built-in from the start rather than added as a complex afterthought, reducing overall device complexity.

AI summary
An image capture device for a secure industrial control system is disclosed. In an embodiment, the image capture device includes: an image sensor; a signal processor coupled to the image sensor; and a controller for managing the signal processor and transmitting data associated with processed image signals to at least one of an input/output module or a communications/control module via a communications interface that couples the controller to the at least one of the input/output module or the communications/control module, wherein the controller is configured to establish an encrypted tunnel between the controller and the at least one of the input/output module or the communications/control module based upon at least one respective security credential of the image capture device and at least one respective security credential of the at least one of the input/output module or the communications/control module.
