Cloud Device Authentication via Physical Proximity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques for authenticating network devices, such as CPEs and access points, are vulnerable to security risks like spoofing, especially when connecting to remote cloud servers, and often require manual configuration which is time-consuming and prone to errors.
Innovation Solution
The described method involves an independent exchange of keys between a cloud server, a network device, and a computing device, ensuring secure authentication and provisioning by verifying the physical proximity and legitimacy of the devices involved.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration is used for network device authentication, then security can be maintained through human verification, but the process becomes time-consuming and error-prone
Solution Approach 1:
The patent implements self-service authentication where the network device autonomously performs authentication with the cloud server without requiring manual configuration. The device automatically exchanges keys, proves physical proximity, and receives provisioning information through automated communication protocols, eliminating the need for human intervention in the authentication process.
Solution Approach 2:
The patent employs preliminary actions by pre-provisioning authentication keys and provisioning information in the cloud server before the actual authentication event. When a network device needs authentication, the system retrieves pre-prepared keys and provisioning data, enabling rapid automated authentication without requiring real-time manual configuration or human verification.
2Productivity
If automated key exchange is implemented between cloud server and network device, then authentication speed improves, but security vulnerabilities to spoofing increase
Solution Approach 1:
The patent introduces an intermediary verification mechanism where a human operator acts as a mediator to verify the physical presence of the network device before automated key exchange occurs. The operator visually confirms the device's physical presence, providing a human element that prevents automated spoofing attacks while maintaining the speed benefits of automated authentication through subsequent key exchange protocols.
Solution Approach 2:
The patent replaces manual mechanical verification processes with automated electronic key exchange mechanisms. Once physical presence is confirmed through visual verification, the system substitutes manual configuration steps with automated cryptographic key exchange protocols, achieving both security through verification and speed through automation.
3Measurement precision
If human verification is required for device provisioning, then authentication accuracy is maintained, but operational complexity increases
Solution Approach 1:
The patent implements self-service provisioning where the network device autonomously completes the provisioning process without requiring manual configuration. The device automatically exchanges keys with the cloud server, receives provisioning information, and configures itself, eliminating the need for human operators to manually configure complex provisioning parameters while maintaining accurate authentication through automated verification.
