Solution Overview

Problem

The integration of hardware trust in wireless relays for data communication networks is not efficient and effective, particularly in providing both hardware-trusted and normal wireless communication services.

Innovation Solution

A wireless relay system that maintains hardware-trusted wireless backhaul links using IEEE 802.11 and LTE connections, validates user equipment (UE) hardware trust, and exchanges user data through hardware-trusted circuitry, broadcasting specific SSIDs and NIDs to differentiate hardware-trusted and normal communication services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless relays offer both hardware-trusted and normal wireless communication services, then service versatility is improved, but system complexity increases

Engineering Contradiction:
Improveservice versatilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the wireless relay system into distinct hardware-trusted and normal communication components. Separate authentication mechanisms, security protocols, and network pathways are established for hardware-trusted services versus standard services. This segmentation allows the system to offer diverse service types while maintaining clear boundaries that prevent complexity from becoming unmanageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different quality standards and security levels to different parts of the system. Hardware-trusted services receive enhanced security validation, dedicated authentication protocols, and stricter verification processes, while normal services operate with standard protocols. This local differentiation of quality and security levels enables service versatility without requiring the entire system to operate at maximum complexity.

Inventive Principle:
Principle #3Local quality

2Reliability

If hardware trust validation is implemented in wireless relays, then communication security is improved, but processing time increases

Engineering Contradiction:
Improvecommunication securityVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements preliminary hardware trust validation during the initial connection establishment phase. By performing authentication and trust verification before actual data transmission begins, the system ensures security without repeatedly validating during ongoing communications. This preliminary action approach secures communications while minimizing time loss to validation processes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent enables UEs to perform self-validation of their hardware trust credentials using pre-shared keys and locally-stored verification data. This self-service approach reduces the processing burden on the wireless relay, as the UE independently verifies its own trustworthiness before establishing connections, thereby enhancing security while reducing overall system processing time.

Inventive Principle:
Principle #25Self-service

3Reliability

If separate hardware-trusted circuitry is used for secure communications, then trust reliability is improved, but device complexity increases

Engineering Contradiction:
Improvetrust reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the hardware-trusted circuitry into the existing wireless relay infrastructure rather than implementing completely separate physical systems. The secure processing functions are integrated within the relay's existing hardware architecture, sharing common components such as processors, memory, and communication interfaces. This merging approach maintains trust reliability through dedicated secure processing while avoiding the complexity increase that would result from entirely separate hardware systems.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A wireless relay (110, 310, 400, 510, 600) serves User Equipment (UE) (101) with hardware- trusted wireless data communications over Institute of Electrical and Electronics Engineers (IEEE) 802.11 links (121, 321, 323) and Long Term Evolution (LTE) links (121, 322, 324). The wireless relay maintains hardware-trusted wireless backhaul links (122, 325, 326) to a data network (120). The wireless relay (110, 310, 400, 510, 600) broadcasts an IEEE 802.11 Service Set Identifier (SSID) (131, 321, 323) and a Long Term Evolution (LTE) Network Identifier (NID) (131, 322, 324). The UE wirelessly transfers a hardware-trusted attachment request (132, 321, 322) using the 802.11 SSID or the LTE NID. The wireless relay (110, 310, 400, 510, 600) validates hardware-trust of the UE (101), and in response, establishes a hardware-trusted attachment of the UE (101). The wireless relay (110, 310, 400, 510, 600) exchanges user data with the UE (101) using hardware-trusted circuitry (401-402, 601-602). The wireless relay (110, 310, 400, 510, 600) exchanges the user data over hardware-trusted wireless backhaul links (122, 325, 326).
