Tachograph Chip Card Authentication for Secure Multi-Function Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tachographs lack versatility and flexibility in their secure data storage and authentication processes, limiting their application beyond their specified operation, and require additional components for user-defined applications, which increases costs and complexity.
Innovation Solution
A digital tachograph with a chip card reading unit that allows user-defined identification information to be securely stored and used for authentication and data storage, enabling secure and cost-effective use of the tachograph's hardware and software for various applications, including secure data transmission and access control, independent of the specified identification information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tachograph uses specified identification information for its designated operation, then security and reliability are improved, but adaptability and versatility deteriorate
Solution Approach 1:
The chip card reading unit is designed to accept both specified identification information (for designated operation) and user-defined identification information (for other applications). The authentication mechanism is universal, allowing the same hardware to verify different types of identification information securely, thus achieving multi-functionality without compromising security.
2Adaptability or versatility
If additional components are added to enable user-defined applications, then adaptability improves, but device complexity increases
Solution Approach 1:
The existing chip card reading unit and authentication mechanism are designed to handle both specified and user-defined identification information, eliminating the need for separate components for user-defined applications. This universal design achieves versatility while maintaining low complexity.
Solution Approach 2:
The patent merges the handling of specified identification information and user-defined identification information into a single authentication mechanism. Both types of identification information are processed through the same chip card reading unit and authentication logic, combining multiple functions into one integrated system.
3Reliability
If the tachograph is designed for specified operation only, then reliability is improved, but ease of operation for multiple applications deteriorates
Solution Approach 1:
The authentication mechanism is designed to universally accept both specified identification information and user-defined identification information. Users can easily insert their chip cards and be authenticated for different applications without needing to understand or configure complex security settings, maintaining ease of operation while ensuring security.

AI summary
A tachograph (TCO) comprises at least one chip card reading unit (CKLE). At least one chip card (CK) with secure memory (MEM_CK) and secured data transmission can be fed to the at least one chip card reading unit (CKLE). On the at least one chip card (CK), at least one user-defined piece of identification information is securely stored which is independent of a specified piece of identification information for a specified operation of the tachograph (TCO). The tachograph (TCO) is constructed so as to authenticate the at least one chip card (CK) in accordance with the at least one piece of user-defined identification information, and to read data securely from the at least one chip card (CK) and/or to store data securely on the at least one chip card (CK).
