Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If formal mechanism for analyzing authentication requirements is introduced, then authentication solution verification capability is improved, but system complexity increases
Solution Approach 1:
The authentication requirement analysis is segmented into distinct functional modules: service specification module captures service parameters, possible service flows representation module models delivery paths, first inference module determines trust levels, second inference module identifies authentication scopes, and valid service flow representation module synthesizes results. This segmentation improves verification capability while managing system complexity through modular design.
Solution Approach 2:
The patent introduces an intermediary authentication requirement analysis system that mediates between ICN service specifications and authentication solutions. This intermediary formally analyzes service parameters, trust relationships, and threat models to generate authentication requirements, enabling systematic verification without directly complicating the authentication solution itself.
2Measurement precision
If comprehensive threat models and trust relationships are analyzed, then authentication requirement accuracy is improved, but analysis time increases
Solution Approach 1:
The patent performs preliminary actions by pre-defining trust relationships, authentication scope definitions, and content delivery options in the service specification phase. Possible service flows are pre-represented based on content nature and delivery options. This preliminary structuring enables faster, more accurate authentication requirement analysis without comprehensive real-time evaluation of all threat models.
Solution Approach 2:
The system changes parameters by representing trust relationships as quantifiable trust levels and authentication scopes as defined parameters. By transforming qualitative security concepts into measurable parameters, the system achieves accurate authentication requirement determination while reducing analysis time through structured parameter evaluation rather than exhaustive threat model exploration.
3Adaptability or versatility
If flexible support for different architectural paradigms is provided, then service adaptability is improved, but mechanism complexity increases
Solution Approach 1:
The patent creates a universal authentication requirement analysis mechanism that supports multiple ICN architectural paradigms (centralized, distributed, hybrid) and various service types (content delivery, publish-subscribe, request-response). The service specification module and inference modules are designed to handle diverse architectures through unified parameter representation, achieving broad adaptability without proportionally increasing mechanism complexity.
Solution Approach 2:
The system dynamically adapts to different architectural paradigms by adjusting its analysis based on service specification parameters. The possible service flows representation and inference modules can reconfigure their analysis approach according to the specific ICN architecture being evaluated, providing flexible support for evolving service sets without requiring separate mechanisms for each paradigm.
Data Source
AI summary
A method, device, and non-transitory computer readable medium for determining and representing one or more authentication requirements for at least one valid service flow of one or more information centric network (ICN) based services. This technique involves capturing service specification and storing it in a repository. Then, one or more possible service flows are generated and represented based on the nature of contents, delivery options and preferred architecture. This representation is again modified based on the trust level among functional entities and authentication scope which are inferred from the service specification. The final representation of the service flow shows only the valid inter-connections and operations among functional entities and the service flow is constrained by authentication requirement.
