Security Transformation Device for Industrial Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial devices in sectors like the oil and nuclear industries are vulnerable to security threats due to unsecured communication lines, allowing malicious actors to inject commands that can disrupt operations, as existing solutions require replacing devices or modifying protocols, which is costly and impractical.
Innovation Solution
A security transformation device is introduced to secure communication between industrial devices and distributed control systems by encrypting and authenticating messages, acting as a gatekeeper to block malicious instructions without altering existing communication protocols or replacing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security transformation device is introduced to encrypt and authenticate communications, then security is improved, but device complexity increases
Solution Approach 1:
A security transformation device is introduced as an intermediary component between industrial devices and the control system. This device transparently encrypts and authenticates communications without requiring modifications to the existing industrial devices or control system, thereby improving security while maintaining compatibility with legacy equipment.
2Reliability
If existing devices are replaced with secure devices, then security is improved, but cost increases
Solution Approach 1:
The security functionality is extracted from the industrial devices themselves and placed into a separate security transformation device. This allows the existing industrial devices to remain unchanged and continue operating with their original communication protocols, while the security functions are implemented in the dedicated security device that can protect multiple devices simultaneously.
3Reliability
If communication protocols are modified to enhance security, then security is improved, but adaptability decreases
Solution Approach 1:
The communication system is segmented into two layers: the original industrial communication layer that maintains protocol compatibility, and a new security layer implemented by the security transformation device that handles encryption and authentication. This segmentation allows security enhancements without disrupting the existing communication protocols or requiring device modifications.

AI summary
A system and associated method for securing communication between a first device and a second device are provided. The system includes a first device communicatively coupled with a second device over a communication connection line. The system includes a security transformation device coupled to the communication connection line. The security transformation device is configured to transform non-secure communication into secure communication to send over the communication connection line to a destination. The security transformation device is configured to evaluate communication using security evaluation functionality by either authenticating or failing to authenticate the communication. If the communication is successfully authenticated, then the communication is provided to a destination, otherwise, the communication is not provided to the destination.
