Intermediate Server for User Equipment Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for integrating new user equipment into an information system are cumbersome and inflexible, requiring secure certificate distribution and limiting the choice of connected objects due to authentication complexities.
Innovation Solution
A method that uses an intermediate server to authenticate user equipment by transmitting test instructions based on its capabilities, leveraging already authenticated devices in the local area network to ensure secure integration into the information system, allowing only authorized communication until full authentication is complete.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If factory certificates are distributed through secure channels to manufacturers, then authentication security is maintained, but logistics become cumbersome and inflexible
Solution Approach 1:
The patent introduces an intermediate server as a mediator between the information system and user equipment. This server handles the authentication process by receiving capability information from new equipment, comparing it with authenticated equipment in the network, and determining authentication without requiring direct certificate distribution to manufacturers. This eliminates the cumbersome logistics of secure certificate distribution while maintaining authentication security through the intermediary's verification process.
2Reliability
If factory certificates are required for authentication, then security is ensured, but the choice of connected objects is limited
Solution Approach 1:
The patent enables user equipment to authenticate itself by providing capability information to the intermediate server, which then compares this information with that of authenticated equipment already in the network. This self-service authentication mechanism eliminates the need for pre-distributed factory certificates, allowing any device regardless of manufacturer to join the network as long as it demonstrates compatible capabilities, thus expanding device variety while maintaining security.
Solution Approach 2:
The patent shifts the authentication parameter from static factory certificates to dynamic capability information. Instead of verifying pre-assigned certificates, the system evaluates the functional capabilities that user equipment can perform and compares them with authenticated equipment. This parameter change allows diverse devices with different manufacturers but similar capabilities to be authenticated, increasing adaptability while maintaining security through capability verification.
3Reliability
If an intermediate server controls message exchanges, then security is enhanced by isolating unauthenticated equipment, but system complexity increases
Solution Approach 1:
The patent segments the system into distinct functional components: an intermediate server layer that handles authentication and message control, and the core information system that remains isolated. The intermediate server acts as a buffer zone that receives and processes authentication requests from unauthenticated equipment, controlling message exchanges in this intermediate layer while keeping the main information system secure and simple. This segmentation enhances security by isolating unauthenticated equipment without significantly increasing the complexity of the core system.

AI summary
Methods for authenticating and integrating user equipment into an information system, corresponding devices and computer programs. Integration of new user equipment into an operator's information system uses communication protocols providing the authentication of the user equipment and guaranteeing integrity and confidentiality of messages exchanged between the user equipment and a user equipment management server of the information system. The user equipment is provided, at the time of manufacture, with an authentication certificate supplied to the manufacturer by the operator managing the information system in which the equipment is to be integrated. This requires cumbersome and inflexible logistics to implement and limits the choice of users as to which user equipment they might wish to integrate. The proposed solution relies on an ecosystem of already authenticated user equipment present in the local network in order to authenticate the user equipment and thus authorize its integration into the information system.
