Solution Overview
Problem
Existing remote access security methods, particularly relying on static passwords, are insufficient for ensuring the authenticity and integrity of users and transactions over computer networks, necessitating a more advanced and cost-effective authentication solution.
Innovation Solution
A Bluetooth-enabled authentication device that generates dynamic credentials by cryptographically combining a secret key with a dynamic variable, using a Bluetooth connection to securely authenticate users and verify transactions, incorporating features like user approval, biometric verification, and secure messaging techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static passwords are used for authentication, then the system is simple to operate, but security reliability is insufficient
Solution Approach 1:
The patent implements dynamic credentials that change over time or with each authentication event, replacing static passwords. The authentication device generates credentials based on dynamic variables such as timestamps, counters, or random values, making each credential unique and time-sensitive. This dynamic approach significantly improves security while maintaining user convenience through automated generation.
Solution Approach 2:
The patent introduces an authentication device as an intermediary between the user and the system being accessed. This device securely stores secret keys and generates credentials, acting as a mediator that enhances security without requiring the user to directly manage complex cryptographic operations. The intermediary handles the complexity while providing a simple user interface.
2Reliability
If advanced security technology is implemented, then authentication reliability improves, but device complexity increases
Solution Approach 1:
The authentication device is self-contained and autonomously generates credentials using internally stored secret keys and dynamic variables. It performs cryptographic operations independently without requiring external computational resources, thereby improving security while avoiding the complexity of integrating multiple external security components.
Solution Approach 2:
The authentication device is designed to work with multiple systems and protocols through standardized interfaces. It can generate various types of credentials (one-time passwords, digital signatures, tokens) and interface with different authentication protocols, reducing overall system complexity by providing a universal security solution that eliminates the need for multiple specialized security devices.
3Reliability
If dynamic credentials are generated and transmitted, then security against unauthorized access improves, but data transmission requirements increase
Solution Approach 1:
The patent extracts only the essential authentication elements (dynamic credentials or signatures) from the full authentication context and transmits only these minimal necessary data elements. The authentication device generates credentials that encapsulate the verification of user identity and transaction integrity in compact forms, reducing data transmission requirements while maintaining high security and integrity verification capabilities.
