Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in authenticating devices within subnetworks, especially when there is no connection to an operator network, and there is a need for efficient and secure authentication methods that maintain independence from such networks.
Innovation Solution
A method and apparatus for authenticating devices within subnetworks using cryptographic key pairs, challenge-response processes, and certificates, allowing devices to verify authenticity and establish trust relationships without relying on direct connections to operator networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices use traditional authentication methods requiring connection to operator network, then authentication security is maintained through centralized control, but network independence and flexibility are reduced
Solution Approach 1:
The patent segments the authentication system into distributed subnet-level authentication units that operate independently without requiring centralized operator network control. Each subnet can perform authentication locally using distributed ledger technology, dividing the authentication function from the traditional centralized architecture.
Solution Approach 2:
The patent implements preliminary authentication setup where devices and subnets establish cryptographic credentials and register authentication capabilities in advance on the distributed ledger. This preliminary action enables authentication to proceed independently without real-time operator network intervention.
2Adaptability or versatility
If devices authenticate without operator network connection, then network flexibility and independence are improved, but authentication reliability and security verification may be compromised
Solution Approach 1:
The patent introduces a distributed ledger as an intermediary that verifies authentication credentials and maintains a trusted record of authenticated devices and subnets. This intermediary enables reliability verification without requiring direct connection to the operator network, as the ledger serves as a decentralized trust anchor.
Solution Approach 2:
The patent creates cryptographic copies of authentication credentials (digital certificates, public keys) that can be verified anywhere on the distributed ledger. These cryptographic copies enable authentication verification to be replicated across multiple subnets without centralized intervention, maintaining reliability through cryptographic verification.
3Ease of operation
If centralized authentication through operator network is used, then authentication security is ensured, but device complexity and authentication overhead increase
Solution Approach 1:
The patent enables subnets and devices to perform authentication autonomously using locally stored cryptographic credentials and distributed ledger verification. Each subnet acts as its own authentication service provider, eliminating the need for complex centralized authentication protocols and reducing operational complexity.

AI summary
A method for a device, in particular terminal device, for a subnet of a wireless communication system. The method includes: sending a request to transmit first information, in particular to a unit, in particular a control unit for the subnet, wherein the first information makes it possible to verify an authenticity of at least one unit associated with the subnet; and receiving a response including at least the first information.
