Wireless Service Authentication Using User and Device Trust Indices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network systems lack effective mechanisms for dynamical trust-based authentication between service consumers and producers, which can lead to security vulnerabilities and unauthorized access.
Innovation Solution
Implementing a trust management function (TMF) that authenticates and authorizes users and devices using user trust indices (UTI) and device trust indices (DTI) to ensure secure service interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication mechanisms are used in wireless networks, then device compatibility and ease of operation are maintained, but security reliability and protection against unauthorized access deteriorate
Solution Approach 1:
The system performs preliminary trust index calculations and authentication assessments before actual service access. The service producer calculates trust indices for service consumers in advance, and authentication results are pre-determined based on these indices, enabling secure access without complex real-time authentication procedures.
Solution Approach 2:
Trust indices serve as an intermediary mechanism between service consumers and service producers. Instead of direct complex authentication, the trust index acts as a mediator that quantifies reliability, allowing the system to make authentication decisions based on this intermediate metric rather than through cumbersome direct verification processes.
2Reliability
If dynamic trust-based authentication is implemented, then security and unauthorized access protection are improved, but system complexity and computational requirements worsen
Solution Approach 1:
The system changes the parameter of authentication from binary (authorized/not authorized) to continuous (trust index values). By calculating and comparing trust indices against thresholds, the system achieves dynamic authentication security without requiring complex multi-factor authentication protocols, reducing overall system complexity while improving reliability.
3Measurement precision
If trust index calculation and verification processes are added, then authentication accuracy and security assessment are improved, but processing time and service response time worsen
Solution Approach 1:
Trust index calculations are performed in advance before service requests are processed. The service producer maintains updated trust indices for service consumers, so when a service request arrives, the authentication decision can be made quickly by comparing the pre-calculated trust index against required thresholds, minimizing service response time while maintaining high authentication accuracy.

AI summary
Procedures are directed to dynamical trust-based authentication for request/response service interaction. A service consumer with an associated user and device may send, to a service producer, a service operation request message requesting access to a target service. The service operation request message may include a first indication indicating that the user and the device will use a trust index of the service producer and a second indication indicating that the user and the device support authentication using a user trust index of the user and/or a device trust index of the device. The service consumer may receive, from the service producer, an authentication notification message including an indication of a trust-based authentication result, and may respond with an authentication confirmation message. The service consumer may receive, from the service producer, a service operation response message including a service execution result associated with the executed target service.
