Secure Storage Authentication for Multi-Provider Control Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of service provision models, where multiple service providers from different industries collaborate, poses challenges in ensuring secure and responsible service delivery, particularly in integrating information and communication technology (ICT) with other sectors like automotive, where safety and security are paramount.
Innovation Solution
A control system comprising an authentication apparatus and a control apparatus with a secure storage unit, which authenticates service providers and records authenticated information, enabling secure control of services and demarcation of responsibility across multiple providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple service providers are integrated into a single control system, then service versatility and functionality are improved, but system complexity and security management difficulty increase
Solution Approach 1:
The system is segmented into distinct functional modules: authentication apparatus for security verification, secure storage unit for credential management, and control apparatus for service execution. This segmentation allows multiple service providers to be integrated while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
An authentication apparatus acts as an intermediary between service providers and the control system. This mediator verifies credentials from multiple providers centrally, enabling service versatility without proportionally increasing the complexity of each individual service integration.
2Reliability
If authentication information is stored in a centralized secure storage unit, then service security and reliability are improved, but the risk of centralized failure and loss of information increases
Solution Approach 1:
The secure storage unit implements local quality through access control mechanisms where different service providers have restricted access only to their specific authentication information. This localization of access rights enhances security while reducing the impact of potential failures to specific service modules rather than the entire system.
3Reliability
If separate authentication is performed for each service provider, then responsibility demarcation and security control are improved, but authentication processing time and system overhead increase
Solution Approach 1:
Authentication credentials are verified in advance by the authentication apparatus before service access is granted. This preliminary authentication action establishes responsibility demarcation upfront, allowing subsequent service operations to proceed without repeated authentication delays.
