Network Trust Assessment Profiles for Cross-Scenario Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of ensuring network security and trustworthiness in heterogeneous networks, particularly in future networks like 6G, is exacerbated by the difficulty in unifying trust level assessment models across diverse scenarios, stakeholders, and domains, leading to interoperability issues.
Innovation Solution
A trust assessment method and system that utilizes a trust level assessor (TLA) to evaluate network devices based on customizable TLA profiles, incorporating claim lists and metadata to determine trust levels, ensuring flexibility and interoperability through the use of trust level assessment certificates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unified trust classification model is used across all scenarios, then network security management is simplified, but it cannot meet the diverse interests and requirements of different countries, regions, operators, and device vendors
Solution Approach 1:
The patent segments the unified trust assessment model into multiple scenario-specific models (e.g., network security scenarios, cloud computing scenarios, IoT scenarios). Each scenario has its own customized trust assessment model that can be independently configured and adapted to meet specific requirements of different countries, regions, operators, and device vendors, while still being part of an overall unified framework.
Solution Approach 2:
The patent implements dynamic trust assessment models that can be flexibly configured and adjusted based on different scenarios and stakeholder requirements. The models support dynamic parameter adjustment, allowing the same base framework to adapt to varying security policies, trust criteria, and operational contexts across different environments.
2Adaptability or versatility
If customized trust assessment models are used for different scenarios, then specific scenario requirements are met, but cross-domain and cross-scenario interoperation becomes difficult
Solution Approach 1:
The patent designs a universal trust assessment framework that can serve multiple scenarios and domains. The framework defines common trust assessment concepts, data structures, and evaluation criteria that are applicable across network security, cloud computing, IoT, and other scenarios. This universal framework enables cross-domain and cross-scenario interoperation while still allowing scenario-specific customizations through configurable parameters and modules.
3Reliability
If a unified trust level assessment model is implemented, then industry consensus is achieved, but it is difficult to accommodate diverse interests of different stakeholders
Solution Approach 1:
The patent applies local quality by allowing different stakeholders (countries, regions, operators, device vendors) to configure and customize trust assessment parameters, criteria, and weights according to their specific interests and requirements within the unified framework. Each stakeholder can define local trust assessment policies that reflect their specific security concerns and operational contexts while maintaining compatibility with the overall industry consensus framework.

AI summary
This application provides a trust assessment method and system, and a related device. The method includes: A trust level assessor TLA performs trust assessment on a trustee based on a first trust level assessment TLA profile and evidence submitted by the trustee, to obtain a trust level of the trustee. The evidence includes one or more claims, and the one or more claims are used to describe related information of the trustee. The first TLA profile includes a plurality of trust levels and an assessment model corresponding to each trust level. The assessment model corresponding to each trust level includes a verification result of one or more claims required by the trust level. The trust assessment system and method provided in this application can be used for trust assessment of a network device in different network scenarios, to resolve a problem that trust level assessment models in different scenarios in a heterogeneous network cannot be unified. In this way, a trust level assessment method with certain flexibility and interoperability can be provided, to ensure network security and trustworthiness.
