Access Control Device for Electronic Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices cannot control access rights for combinations of electronic devices in a network, limiting their ability to manage access permissions for applications that interact with multiple devices.
Innovation Solution
An access control device and method that generate and manage authority and permission information for electronic devices, allowing precise control of access rights across multiple devices in a network by using an authority information generating section, permission information generating section, and communication sections to ensure authorized access and prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electronic devices control access to all networks (i.e., all devices), then security is improved, but device complexity increases and flexibility is reduced
Solution Approach 1:
The patent segments access control by introducing combination-specific permission information for different electronic device pairs. Instead of uniform access control, the system divides permissions into device-specific combinations, allowing fine-grained control over which devices can access which resources, thereby reducing unnecessary complexity while maintaining security.
Solution Approach 2:
The patent applies local quality by assigning different permission levels to different device combinations. Each electronic device receives tailored permission information specific to its interactions with other devices, rather than applying a blanket access control policy across all devices. This allows security to be optimized locally for each device pair.
2Reliability
If conventional electronic devices control access to all networks, then unauthorized access is prevented, but adaptability to different service scenarios is reduced
Solution Approach 1:
The patent introduces dynamic adaptability by allowing access permissions to be flexibly configured for different service scenarios and device combinations. The system can adapt permission settings based on specific service requirements, enabling the same access control mechanism to serve multiple different use cases without requiring uniform restrictive policies.
3Reliability
If conventional electronic devices use authentication information to control access, then security is improved, but the ability to manage组合-specific permissions is reduced
Solution Approach 1:
The patent adds a new dimension to access control by introducing combination-specific permission information that operates alongside traditional authentication. This creates a multi-layered permission system where authentication verifies identity while combination-specific permissions control access rights for particular device pairs, making permission management more flexible and intuitive.

AI summary
An access control device controls an access right with respect to a plurality of electronic devices in a network for each combination of electronic devices. An authority information generating section generates authority information which is used when an electronic device accesses an application on an electronic device. A permission information generating section generates permission information which is information about whether or not the electronic device permits an access request from the electronic device, in relation with the authority information. An access information storing section stores the authority information and the permission information. A transmission control section transmits via the communication section the authority information to the electronic device and the permission information to the electronic device.
