eSIM Registration Using Profile-Based Authentication Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current password-based authentication for ESIM cards is insecure due to non-unique and easily forgeable passwords burnt by terminal manufacturers, leading to low registration security.
Innovation Solution
A configuration identifier and password are generated based on the ESIM card's profile, with the configuration identifier uniquely identifying the card and ensuring high security, eliminating the need for manufacturers to burn passwords into terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a password is burnt into the terminal by the manufacturer for authentication, then authentication can be performed, but the password becomes non-unique and easily forgeable, leading to low security
Solution Approach 1:
The patent extracts the password generation process from the manufacturer's production line and relocates it to the terminal's runtime operation. The password is no longer burnt into the terminal during manufacturing but is generated dynamically by the terminal itself using its unique identifier, thereby eliminating the security vulnerabilities of pre-burnt passwords while simplifying the manufacturing process.
Solution Approach 2:
The terminal generates its own authentication password autonomously based on its unique identifier without requiring external intervention from the manufacturer. This self-service mechanism ensures that each terminal produces a unique, secure password that cannot be easily forged, while also eliminating the need for complex password burning infrastructure.
2Reliability
If a password is burnt into the terminal by the manufacturer, then authentication is enabled, but the process increases production complexity and security risks
Solution Approach 1:
The patent removes the password burning step from the production process entirely. Instead of incorporating password burning equipment and procedures into the manufacturing line, the system extracts this function and implements it software-based in the terminal at runtime, thereby reducing production device complexity while maintaining or improving security.
Solution Approach 2:
The patent replaces the physical/mechanical password burning process with a software-based cryptographic generation process. The terminal uses its unique identifier and a cryptographic algorithm to generate the password, substituting hardware-level password injection with software-level cryptographic operations, which reduces manufacturing complexity.
3Productivity
If manufacturers burn passwords into terminals, then authentication can be performed, but this creates security risks and reduces production efficiency
Solution Approach 1:
The patent extracts the password generation function from the manufacturing process, allowing terminals to be produced without the time-consuming and security-risky password burning step. The password is generated later by the terminal itself, which accelerates production while eliminating security vulnerabilities.
Solution Approach 2:
The terminal stores its unique identifier in advance during manufacturing, which serves as the seed for future password generation. This preliminary action enables rapid password creation at runtime without requiring complex real-time computation or external authentication during the registration process.

AI summary
This application discloses a registration method and apparatus for an ESIM card, and belongs to the field of terminal technologies. The ESIM card is configured in a terminal. The method is applied to a registration node. The method includes: The registration node obtains a configuration identifier of the ESIM card, where the configuration identifier is obtained based on a profile of the ESIM card, and the ESIM card is obtained by performing configuration based on the profile; the registration node obtains a password of the ESIM card, where the password is generated in a use process of the terminal; and the registration node registers the ESIM card when the configuration identifier matches the password. This application can ensure registration security of the ESIM card.
