Contactless Card Cryptographic Authentication for Storage Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable storage devices pose a security risk due to their compact size, making them easily misplaced or accessed by unauthorized individuals, leading to potential data breaches without adequate security measures.
Innovation Solution
Implementing cryptographic authentication using contactless cards with integrated storage devices, where a cryptogram is generated and verified by a server to unlock the storage device, ensuring secure access through wireless communication and key diversification techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If storage devices are made compact and portable, then ease of operation and mobility are improved, but security and risk of unauthorized access deteriorate
Solution Approach 1:
The storage device is pre-configured with cryptographic authentication mechanisms, including encryption keys and authentication protocols, before deployment. This preliminary setup enables automatic security verification when the device is accessed, preventing unauthorized access without requiring user intervention or reducing portability.
2Object-affected harmful factors
If cryptographic authentication is implemented, then security against unauthorized access is improved, but device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical or manual authentication methods (such as physical keys or password prompts) with cryptographic authentication using encryption algorithms and digital signatures. This substitution provides stronger security while maintaining a streamlined user interface, as the cryptographic verification occurs automatically in the background without adding visible complexity to the device operation.

AI summary
Systems, methods, apparatuses, and computer-readable media for cryptographic authentication to control access to storage devices. An applet executing on a processor of a contactless card may receive, via a wireless communications interface of the contactless card, a request to access a storage device of the contactless card, where the storage device is in a locked state. The applet may generate a cryptogram based on the request and transmit the cryptogram to a computing device via the wireless communications interface. The applet may receive, from the computing device, an indication specifying that a server decrypted the cryptogram. The applet may transmit, to a controller of the storage device and based on the indication specifying that the server decrypted the cryptogram, an indication specifying to unlock the storage device. The controller may transition the storage device from the locked state to an unlocked state based on the indication received from the applet.
