Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems lack effective methods to assert the trustworthiness of wireless transmit/receive units (WTRUs) in relay applications, particularly in proximity-based services, which can compromise network security and reliability.
Innovation Solution
Implementing methods and systems for asserting the trustworthiness of WTRUs through proximity-based services (ProSe) and network relay applications, utilizing procedures such as remote attestation and key management functions to verify the integrity and reliability of relay WTRUs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If WTRU trustworthiness assertion mechanisms are implemented in relay applications, then network security and reliability are improved, but device complexity and operational overhead increase
Solution Approach 1:
The patent introduces a Proxy Mobile IPv6 (PMIP) network entity as an intermediary that performs trustworthiness verification of relay WTRUs. Instead of requiring direct complex verification between all WTRU pairs, the PMIP network entity centralizes the verification process, acting as a trusted mediator that authenticates relay nodes and manages security contexts. This resolves the contradiction by maintaining high security (improving feature) while reducing device-side complexity (mitigating worsening feature) through network-side mediation.
Solution Approach 2:
The patent implements feedback mechanisms where the PMIP network entity receives verification results from relay WTRUs and provides authentication decisions back to communicating WTRUs. Trustworthiness information is fed back through the network infrastructure, allowing WTRUs to make informed relay selection decisions without performing complex verification themselves. This maintains security through continuous verification feedback while simplifying device operations.
2Reliability
If comprehensive trust verification procedures are performed for relay WTRUs, then communication integrity is improved, but processing time and operational overhead increase
Solution Approach 1:
The patent performs trustworthiness verification as a preliminary action during relay WTRU registration and connection establishment phases. The PMIP network entity verifies the identity and trustworthiness of relay WTRUs before they are allowed to participate in relay operations. By performing verification in advance rather than in real-time during communication, the system ensures communication integrity (improving feature) while minimizing time loss during actual data transmission (mitigating worsening feature).
Solution Approach 2:
The patent implements dynamic trust verification where the depth and scope of verification procedures adapt based on the communication context, WTRU profiles, and security requirements. Not all relay scenarios require the same level of verification - the system dynamically adjusts verification intensity, performing comprehensive checks when needed and streamlined verification for trusted, established relays. This maintains communication integrity while reducing average verification time through contextual adaptation.
