IoT Device Control via Cloud Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for device control across different Internet of Things (IoT) systems face challenges in secure and efficient authentication and authority setting, particularly when IoT devices from different systems need to interact, often requiring costly security measures and struggling with protocol interconnection stability and standardization.
Innovation Solution
A method for setting device control authority involves receiving access information from a second IoT device, obtaining and authenticating a cloud server's device authentication information, and subsequently setting authority information for the first IoT device, enabling secure device control across systems without the need for local security chips or certificates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security measures (security chips, certificates) are used for device control across different IoT systems, then security is improved, but device cost and complexity increase
Solution Approach 1:
The patent introduces a cloud server as an intermediary to perform authentication between IoT devices from different systems. Instead of requiring direct authentication between devices (which would need complex local security mechanisms), the cloud server mediates the authentication process by verifying device identities and issuing access tokens, thereby reducing local device complexity while maintaining security.
Solution Approach 2:
The patent replaces physical security mechanisms (security chips, hardware certificates) with a software-based authentication system running on cloud servers. This substitution eliminates the need for expensive hardware security components in each device while achieving equivalent or superior security through centralized credential verification and token-based access control.
2Adaptability or versatility
If protocol interconnection methods are used to enable devices from different IoT systems to communicate, then adaptability is improved, but system stability and security worsen due to lack of standardization
Solution Approach 1:
The patent creates a universal authentication framework that works across different IoT systems and protocols. The cloud server implements a standardized authentication interface that can handle various device types and communication protocols, allowing devices from different manufacturers and systems to interoperate securely without requiring protocol-specific security implementations.
Solution Approach 2:
The patent changes the authentication parameter from device-specific hardware credentials to cloud-verified access tokens. This parameter transformation allows the system to maintain standardized authentication procedures while supporting diverse device protocols, as the token-based approach abstracts away protocol differences and provides a uniform security layer.

AI summary
The present application provides a configuration method for a device control privilege, an apparatus, a device, and a storage medium. Access information for a second cloud server sent by a second internet of things device that has established a connection relationship with a first internet of things device is received, and device authentication information of the second cloud server is obtained according to said access information; authentication is performed on the second cloud server on the basis of the device authentication information; and if authentication is passed, privilege information of the second internet of things device with respect to the first internet of things device is configured.
