Master Supplicant Authentication Aggregation for Signal Conflict Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication protocols, such as EAP-SIM, face challenges in efficiently authenticating multiple devices due to signal conflicts and duplicate operations, particularly in multi-hop relay networks, leading to ineffective authentication processes.
Innovation Solution
An authentication method where multiple devices cooperate by using a master supplicant and slave supplicants, with an authenticator, to execute authentication procedures efficiently, utilizing EAP-SIM protocol extensions and data aggregation techniques to manage authentication signals and keys across different communication networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple supplicants perform authentication operations independently with the authenticator, then each supplicant can be authenticated, but signal conflicts and duplicate operations occur leading to ineffective authentication
Solution Approach 1:
The patent introduces a master supplicant as an intermediary device that mediates between slave supplicants and the authenticator. The master supplicant aggregates authentication messages from multiple slave supplicants and communicates with the authenticator on their behalf, eliminating signal conflicts and duplicate operations while ensuring reliable authentication of all supplicants.
2Ease of operation
If authentication operations are executed at independent timing for each supplicant, then individual authentication can be performed, but authentication efficiency decreases due to repeated operations
Solution Approach 1:
The patent merges authentication operations by having the master supplicant aggregate authentication messages from multiple slave supplicants into a single communication stream with the authenticator. This combining of operations maintains individual authentication capability while dramatically improving efficiency by eliminating repeated independent authentication sequences.
3Adaptability or versatility
If traditional EAP-SIM protocol is used for multiple supplicants, then authentication can be attempted, but the protocol complexity increases and effectiveness decreases
Solution Approach 1:
The master supplicant serves as an intermediary that translates multiple slave supplicants' authentication requests into a standardized EAP-SIM protocol format compatible with the authenticator. This intermediary approach enables multi-supplicant support while maintaining protocol simplicity, as the master supplicant handles the complexity of coordinating multiple devices.
