Network Access Control via Customized Node Capability Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network access methods allow nodes with insufficient technical characteristics to join, degrading network performance by compromising computation capacity, data transmission, and other qualities.
Innovation Solution
A customized test-based access control method where a 'challenging node' defines and sends a test to a 'challenged node' to assess its technical capabilities, with results determining network access, ensuring nodes meet specific quality standards such as computation capacity, latency, and energy efficiency.

Engineering Contradiction Analysis
1Loss of time
If a new node sends a request for access and joins after authentication, then the node can access the network quickly, but the node may have insufficient technical characteristics and degrade network performance
Solution Approach 1:
The patent applies preliminary action by conducting capability tests before final network access approval. The challenging node sends test requests to the challenged node, evaluating computation capacity, data transmission capability, and other technical characteristics. Only after successful completion of these preliminary tests is the challenged node authorized to join the network, thus preventing nodes with insufficient capabilities from degrading network performance while still providing relatively quick access through automated testing.
2Reliability
If a customized test is executed to evaluate node capabilities, then network performance is maintained, but the access control process becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the access control process into distinct functional modules: a test definition module that creates capability tests, a test execution module that runs the tests on challenged nodes, and a result evaluation module that determines access authorization. This modular segmentation manages complexity by organizing the access control system into independent, manageable components with clear interfaces, making the overall process more tractable while maintaining comprehensive node evaluation.
3Manufacturing precision
If multiple tests are conducted to ensure quality standards, then node quality is guaranteed, but the access time increases
Solution Approach 1:
The patent applies partial or excessive action by implementing a tiered testing approach where the challenging node can send one or multiple test requests depending on network requirements and node capabilities. The system performs sufficient testing to guarantee quality standards (computation capacity, data transmission, etc.) without unnecessarily excessive testing that would prolong access time. The number and complexity of tests are adjusted to match the specific requirements, achieving quality assurance with minimal necessary time investment.

AI summary
Devices and methods for accessing and for controlling access of a node, called “challenged node”, that has already been authenticated and is provisionally connected to a network of nodes, the network including at least one node, called “challenging node”. The method for controlling access, implemented by a challenging node, includes: defining a personalized test that must be executed by the challenged node; sending the test to the challenged node; receiving, from the challenged node, at least one result of the execution of the test; and authorizing or refusing the access of the challenged node to the network, at least on the basis of the result.
