Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current access control systems face inefficiencies and security issues when providing API credentials to client machines across multiple networks, as they cannot verify the identity and characteristics of client devices located in separate networks, leading to potential unauthorized access.
Innovation Solution
Implementing a satellite component of the access control system within each client device's network to verify device characteristics through interaction with a management entity, generating a signed document that is trusted by the access control system, and providing it to the client for accessing secure resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual credential transfer is used to provide API credentials to client machines, then security issues are introduced and inefficiency occurs, but automated distribution across multiple networks cannot be implemented due to inability to verify device identity
Solution Approach 1:
A satellite component is introduced as an intermediary between the access control system and client devices on remote networks. This satellite verifies device characteristics and issues signed documents that enable automated credential distribution without manual intervention, while maintaining security through cryptographic verification of device identity.
Solution Approach 2:
The access control system is segmented into a central access control system and distributed satellite components deployed in different networks. Each satellite independently verifies devices in its local network, enabling scalable automated credential distribution across multiple networks while the central system maintains overall control and policy enforcement.
2Device complexity
If access control system is centralized in one network, then control and policy enforcement is simplified, but it cannot verify devices on separate networks leading to potential spoofing
Solution Approach 1:
The satellite component acts as a trusted intermediary that the central access control system can rely on for remote device verification. The satellite's signed documents provide cryptographic proof of device characteristics, allowing the centralized system to enforce policies remotely without direct access to the device's local network management entities.
Solution Approach 2:
The system extends verification capabilities from the local network dimension to the remote network dimension by deploying satellite components in different networks. This dimensional expansion allows the centralized access control system to verify devices across network boundaries without compromising structural simplicity.
3Reliability
If API credentials are provided manually through email or file handover, then automated processes are avoided, but resource efficiency decreases and security risks increase
Solution Approach 1:
Client devices automatically obtain credentials through the satellite-based verification process without requiring manual credential transfer. The device presents its characteristics, the satellite verifies and signs the credential request, and the device receives credentials automatically, eliminating manual intervention and improving both security and efficiency.
Solution Approach 2:
The manual mechanical process of credential transfer via email or file handover is replaced with an automated electronic verification and distribution system. Cryptographic verification and digital signature mechanisms substitute for manual authentication processes, enabling secure automated credential distribution.
