Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial control systems face security vulnerabilities, particularly with image capture devices like cameras, which can be exploited by malicious actors for unauthorized access or malware introduction, compromising the system's integrity.
Innovation Solution
Implementing image capture devices with an image sensor, signal processor, and controller 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
1Adaptability or versatility
If image capture devices are integrated into industrial control systems, then monitoring and surveillance capabilities are improved, but security vulnerabilities increase due to potential unauthorized access and malware introduction
Solution Approach 1:
The patent introduces an authentication sequence as an intermediary mechanism between the image capture device and the industrial control system. This authentication process acts as a mediator that verifies the legitimacy of devices before allowing communication, thereby maintaining monitoring capabilities while blocking unauthorized access and malware introduction
2Reliability
If authentication sequences and encrypted tunnels are implemented, then system security is improved, but device complexity increases
Solution Approach 1:
The patent implements authentication sequences as preliminary actions that occur before normal operation begins. By performing security verification in advance, the system establishes encrypted tunnels and validates devices prior to data transmission, ensuring security without adding complexity to the ongoing operational流程
Solution Approach 2:
The patent extracts the security functionality into a separate authentication sequence that operates independently from the main image capture and transmission functions. This separation allows the core imaging operations to remain simple while security protocols are handled through distinct authentication and encryption mechanisms

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.
