Remote IoT Device Management for Automated Credential Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The initial setup of authentication information for a large number of IoT devices is costly and time-consuming, especially as the number of connected devices increases, leading to increased manufacturing costs.
Innovation Solution
A method for remotely managing devices involves receiving a device ID and an identification number via a cellular network, obtaining a customer ID, generating a credential based on this information, and transmitting initial setting information to establish a secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication information is provided in advance for each device before use, then secure connection with the management server is established, but the man-hours in the manufacturing process increase leading to increased costs
Solution Approach 1:
The patent applies preliminary action by pre-storing identification numbers (IMSI) in SIM cards during manufacturing, and pre-establishing a database that maps identification numbers to customer IDs and authentication information. This allows devices to automatically retrieve their authentication credentials upon first connection without requiring manual configuration during manufacturing, thus maintaining security while reducing manufacturing time and costs.
Solution Approach 2:
The patent implements self-service by enabling devices to automatically retrieve their own authentication information from the management server using their pre-stored identification numbers. The device autonomously completes the authentication setup process without human intervention, eliminating the need for manual configuration of authentication information during manufacturing while ensuring secure connections are established.
2Reliability
If authentication information is manually configured for each device, then secure communication is established, but the number of man-hours required increases as the number of devices increases
Solution Approach 1:
The patent applies preliminary action by pre-storing identification numbers in SIM cards during manufacturing and pre-configuring a database with the mapping between identification numbers and authentication information. This setup occurs once during system initialization, allowing subsequent device onboarding to occur automatically without manual configuration, thus reducing setup time while maintaining secure communication.
Solution Approach 2:
The patent implements self-service by enabling devices to automatically retrieve their authentication information from the management server using their pre-stored identification numbers. The device autonomously completes the authentication setup process without human intervention, significantly reducing the time required for device setup while ensuring secure communications are established.
3Reliability
If authentication information is pre-provided for each device, then secure connection is established, but the cost of initialization increases as the number of devices increases explosively
Solution Approach 1:
The patent applies preliminary action by pre-storing identification numbers in SIM cards during manufacturing and pre-establishing a database that maps identification numbers to authentication information. This one-time setup during system initialization allows subsequent device onboarding to occur automatically without requiring manual configuration, thus maintaining secure connections while preventing initialization costs from increasing linearly with the number of devices.
Solution Approach 2:
The patent implements self-service by enabling devices to automatically retrieve their authentication information from the management server using their pre-stored identification numbers. The device autonomously completes the authentication setup process without human intervention, eliminating the need for manual configuration costs and preventing initialization costs from increasing explosively with the number of devices while ensuring secure connections.

AI summary
A method for remotely managing a device involving receiving an initial setting request including a device ID of a device together with an identification number for connecting to a cellular network or a corresponding ID via the cellular network from the device on which the identification number is stored, obtaining a customer ID corresponding to the identification number based on the identification number or the corresponding ID, generating a credential for the device using the customer ID and the device ID, and transmitting initial setting information including the credential or corresponding authentication information to the device.
