Solution Overview

Problem

The security of password-based authentication for ESIM cards is low due to insecure password burning by terminal manufacturers, leading to potential forgery and reduced registration security.

Innovation Solution

A configuration identifier is generated based on the ESIM card's profile, and a password is generated in the terminal's use process, ensuring unique identification and high security, eliminating the need for password burning by manufacturers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If password is burnt into terminal by manufacturer, then terminal can be produced, but security of password-based authentication is low

Engineering Contradiction:
Improveterminal productionVSAvoidauthentication security
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent extracts the password generation process from the manufacturing phase and relocates it to the usage phase. Instead of burning passwords into terminals during production, the system generates passwords dynamically when the terminal is first used, thereby eliminating the security vulnerabilities associated with manufacturer-burnt passwords while maintaining ease of production.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements preliminary actions by pre-configuring the terminal with a seed value during manufacturing, but the actual password generation is deferred until the terminal is first used. This preliminary setup enables easy production while the subsequent dynamic password generation ensures high authentication security.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If configuration identifier is generated based on profile, then authentication security is enhanced, but system complexity increases

Engineering Contradiction:
Improveauthentication securityVSAvoidregistration system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a configuration node as an intermediary component that manages the complex operations of profile storage, configuration identifier generation, and password verification. This intermediary architecture distributes the complexity across a dedicated service layer, simplifying the overall system while maintaining enhanced authentication security through cryptographic operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

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 generated 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.
