IoT Device Authentication Using Unique Account Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT systems face security vulnerabilities due to shared account information among devices, making them susceptible to hacking, which compromises the entire network if one device's account is compromised.
Innovation Solution
An authentication method for IoT devices that calculates unique account information based on an identifier and preset attribute information, which is then sent to a cloud server for identity verification, ensuring that each device has distinct login credentials and reducing the risk of network-wide breaches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If shared account information is used among IoT devices, then device complexity is reduced and ease of operation is improved, but system security deteriorates as one compromised account can lead to network-wide breaches
Solution Approach 1:
The patent divides the shared account system into segmented unique accounts for each device. Instead of one common account for all devices, each device receives its own distinct account information, isolating security risks to individual devices while maintaining ease of automated authentication for each device independently
2Reliability
If unique account information is generated for each IoT device, then system security is improved by isolating compromised devices, but device complexity increases due to individual credential management
Solution Approach 1:
The patent applies preliminary action by pre-generating and binding unique account information to each device's identifier during manufacturing or provisioning. This advance preparation eliminates the need for complex runtime credential management, as devices automatically use their pre-configured unique accounts for authentication without requiring additional complexity

AI summary
The present disclosure provides an authentication method of an IoT device, an IoT device, a cloud server, an IoT authentication system and a computer readable medium. The authentication method includes: calculating account information corresponding to the IoT device according to an identifier and preset attribute information of the IoT device; and sending the account information to a cloud server, to cause the cloud server to perform identity authentication on the IoT device according to the account information.
