Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security protocols are implemented in industrial automation communication systems, then security against network threats is improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent introduces a cloud services platform as an intermediary that handles security protocols, authentication, and encryption/decryption operations. This mediator absorbs the complexity of security implementation from industrial automation devices, allowing them to maintain simple device architectures while still benefiting from robust security through the cloud platform's intermediary services.
Solution Approach 2:
The patent replaces traditional mechanical/security processing approaches at the device level with cloud-based computational security mechanisms. Security operations such as authentication, encryption, and threat detection are substituted from local device processing to remote cloud processing, reducing device complexity while maintaining or enhancing security capabilities.
2Reliability
If security operations are performed on configuration data, then security is improved, but processing time and computational resources increase
Solution Approach 1:
The patent implements preliminary security operations where the cloud services platform pre-authenticates devices, pre-encrypts configuration data, and pre-establishes secure communication channels before actual data transmission occurs. This preliminary action ensures that when configuration data needs to be updated or transmitted, the security verification is already complete, significantly reducing processing time during critical operations.
Solution Approach 2:
The patent establishes continuous secure communication channels between the cloud platform and industrial devices, maintaining persistent authenticated sessions. This continuity eliminates the need for repeated security operations on each data transmission, allowing configuration updates to be applied continuously without intermittent security processing delays.
3Reliability
If industrial devices perform additional processing tasks for security, then security is improved, but computing resources and operational efficiency decrease
Solution Approach 1:
The patent extracts security processing functions from industrial automation devices and relocates them to the cloud services platform. By taking out authentication, encryption, threat detection, and configuration validation operations from the device level and concentrating them in the cloud, the patent eliminates the burden of additional processing tasks on devices, allowing them to focus entirely on their primary operational functions with full security support.
Data Source
AI summary
A method may include receiving, via a secure deployment management (SDM) system, data associated with operations of an industrial device from a SDM node associated with the industrial device. The data is received via a secure communication channel established by the SDM system with the SDM node and security protocols. The SDM node is communicatively coupled with a machine learning system for sending and receiving data. The machine learning system may generate an updated machine learning model based on the data and a machine learning model representative of expected outputs associated with the operations of the industrial device and generate updated configuration data based on the updated machine learning model. The method may then include receiving the updated configuration data from the SDM node via the secure communication channel and sending the updated configuration data to the industrial device without performing security operations on the updated configuration data.
