Solution Overview
Problem
The existing systems for configuring and updating telecommunications chip cards lack secure and efficient methods for customization and authentication, particularly in scenarios where high security and low-cost personalization are required, such as in the developing world or competitive markets.
Innovation Solution
A telecommunications chip card with a chip card processor and secure memory for cryptographic mutual authentication, combined with an update system that includes a terminal device for exchanging data with the chip card, performs cryptographic operations and biometric verification to securely configure and update the chip card, ensuring only authorized modifications and high security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cryptographic mutual authentication and secure memory are implemented in the chip card, then security is improved, but device complexity increases
Solution Approach 1:
The chip card contains a secure memory means that is nested within the card structure, which stores cryptographic keys and authentication data. This nested secure storage enables cryptographic mutual authentication between the terminal device and chip card without requiring complex external security infrastructure, thus improving security while managing device complexity through integrated design.
2Adaptability or versatility
If complete customization of chip cards is enabled, then adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The chip card is pre-configured with a program stored in secure memory that enables cryptographic authentication and customization capabilities. This preliminary preparation allows the card to be fully customized for different telecommunications networks and applications without requiring complex manufacturing processes, as the customization logic is embedded during card production rather than during deployment.
3Reliability
If secure memory means is added to the chip card, then reliability is improved, but manufacturing cost increases
Solution Approach 1:
The secure memory means in the chip card serves multiple functions: storing cryptographic keys, storing customization data, and enabling authentication protocols. This multi-functionality allows a single security component to address various security requirements across different telecommunications applications, improving reliability while controlling manufacturing costs by avoiding the need for separate dedicated security hardware for each function.

AI summary
The invention provides for a telecommunications chip card for logging into a mobile a digital cellular mobile telecommunications network (107). The telecommunications chip card comprises a chip card reader interface for communicating with a mobile telephone device, a chip card processor means, and a secure memory means (302) for storing programs for execution by the chip card processor means. The secure memory means contains a program (304). The program causes the chip card processor means to: perform (200) a first cryptographic mutual authentication between the telecommunications chip card and a terminal device (502), receive (214) a configuration message (400, 402, 404, 406, 408, 410, 524) via the chip card reader interface, store the (216) configuration message in the secure memory means, and delete (218) the program from the secure memory means.
