Charging Access Control Using Mobile Body Security Levels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing use of mobile bodies capable of wireless communication for charging poses security risks due to potential external communication access, compromising confidentiality, integrity, and availability of information.
Innovation Solution
A charging management system that determines a security level based on the mobile body's capabilities, such as software freshness and breach history, to provide preferential treatment, including reservation priority, discounted fees, and increased charging speed, thereby encouraging users to enhance security measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile bodies communicate with the outside via wireless communication link, then convenience of the mobile body is improved, but security problems may occur on the mobile body with respect to communication access from the outside
Solution Approach 1:
The patent applies local quality by providing differentiated charging services based on the security level of different mobile bodies. High-security mobile bodies receive preferential treatment such as reserved charging slots and discounted fees, while low-security ones face restrictions. This localized differentiation in service quality resolves the contradiction by rewarding secure systems without preventing communication functionality.
Solution Approach 2:
The patent changes the parameter of charging service conditions based on the security level parameter of the mobile body. By dynamically adjusting charging fees, available time slots, and priority levels according to security assessments, the system incentivizes mobile bodies to maintain high security while preserving wireless communication capabilities.
2Reliability
If preferential treatment is provided to mobile bodies with high security level, then security incentive is enhanced, but complexity of the charging management system increases
Solution Approach 1:
The patent implements feedback by continuously monitoring the security level of mobile bodies and adjusting charging service conditions accordingly. The charging management server receives security level information, processes it through predetermined criteria, and provides feedback in the form of differentiated charging conditions. This automated feedback loop enhances security incentives while managing system complexity through algorithmic decision-making.
Solution Approach 2:
The system applies self-service by enabling mobile bodies to automatically receive appropriate charging services based on their declared security level. The charging management server autonomously processes security level information and applies corresponding service conditions without manual intervention, reducing operational complexity while maintaining reliability-based differentiation.
