IoT Service Device CASE Connection via Cloud Token
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IoT technologies limit the management and control scenarios for service devices, restricting their convenience and security due to limited network configuration capabilities.
Innovation Solution
A method involving a configuration device that acquires and sends token information to a service device to establish a certificate authenticated session (CASE) connection with a cloud device, enabling secure and remote management and control through a CASE connection using TCP/UDP protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a service device is configured with network configuration through a configuration device to access the network, then the service device can establish internet connection and receive management and controls, but the application scenario is greatly limited and the convenience of management and control is influenced
Solution Approach 1:
The patent introduces a cloud device as an intermediary between the service device and the configuration device. The configuration device obtains token information from the cloud device and transmits it to the service device, which then uses this token to establish a CASE connection directly with the cloud device. This intermediary mechanism enables remote management and control scenarios that were previously limited, while maintaining ease of operation through automated token-based authentication.
2Adaptability or versatility
If management and control by the configuration device on the service device is only concerned in related art, then the system is simple, but the application scenario is greatly limited
Solution Approach 1:
The patent segments the management system into three distinct components: the configuration device for local device management, the cloud device for centralized token issuance and storage, and the service device for executing controlled operations. This segmentation allows the system to expand application scenarios through cloud-based services while keeping each individual device relatively simple in structure and function.
3Reliability
If the service device establishes connection with the cloud device directly without token information, then the connection establishment is simple, but the security and reliability of the connection is compromised
Solution Approach 1:
The patent implements preliminary action by having the configuration device obtain token information from the cloud device before the service device establishes its connection. The token is transmitted to the service device in advance, so that when the service device initiates the CASE connection to the cloud device, the authentication is already prepared. This preliminary token distribution simplifies the actual connection process while ensuring security through pre-configured authentication credentials.
Data Source
AI summary
A method for connection establishment and an Internet of Things (IoT) device are disclosed. The method is performed by a configuration device, including: acquiring token information of a service device from a cloud device; and sending the token information to the service device, the token information being configured for establishing a certificate authenticated session establishment (CASE) connection between the service device and the cloud device.
