Controller-Mediated Component Authentication for Scalable Secure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-theft solutions for devices, such as automobiles, require presetting keys and algorithms in all components with authentication requirements, leading to high development and maintenance costs and limited scalability.
Innovation Solution
A component control method where a second controller performs authentication on a first controller instead of on individual components, allowing the first controller to send control instructions to components only after successful authentication and trusted authentication results, thereby reducing the need for authentication in all components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication is performed on all components with authentication requirements, then security protection is improved, but development and maintenance costs increase
Solution Approach 1:
The patent introduces a controller as an intermediary that performs authentication on behalf of multiple components. Instead of each component having its own authentication mechanism, the controller acts as a centralized authentication authority that verifies components when they request control operations. This reduces the complexity of implementing authentication in every component while maintaining security through the centralized controller's authentication process.
2Reliability
If authentication is performed on all components, then security protection is improved, but the number of components requiring authentication increases
Solution Approach 1:
The controller is designed to perform multiple functions: it not only controls components but also serves as a universal authentication authority for all components. This multi-functionality allows the system to maintain security without requiring dedicated authentication mechanisms in each component, as the controller's authentication capability serves all components universally.
3Reliability
If authentication is performed on individual components, then security is improved, but scalability is limited
Solution Approach 1:
The controller serves as an intermediary that enables scalable system growth. When new components are added to the system, they automatically benefit from the controller's authentication capability without requiring individual authentication implementations. This intermediary approach allows the system to scale efficiently while maintaining consistent security standards across all components.

AI summary
A component control method includes a first controller that sends a control instruction to a component when authentication performed by a second controller on the first controller has succeeded and an authentication result is trusted, and the component responds to the control instruction. Authentication on the component may be transferred to the first controller, and the first controller may control one or more components by using the control instruction.
