Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional authentication methods, such as one-time passcode (OTP) tokens, lack secure and efficient mechanisms for authenticating devices, particularly in scenarios where wireless connections are vulnerable to security breaches and power requirements are a concern.
Innovation Solution
The implementation of Near Field Communication (NFC)-enabled authentication tokens that utilize NFC connections for secure authentication, drawing power from the NFC field and supporting encryption, allowing for secure communication between devices with a short range, reducing the need for additional power sources and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication methods (OTP tokens) are used, then authentication functionality is provided, but security is insufficient and power requirements increase
Solution Approach 1:
The patent replaces conventional mechanical/electronic authentication token systems with an NFC-based electromagnetic field system. The NFC authentication mechanism uses electromagnetic near-field communication to authenticate devices, eliminating the need for separate power sources and physical token handling, thereby improving security while reducing power requirements
Solution Approach 2:
The patent introduces NFC technology as an intermediary mechanism between devices for authentication purposes. The NFC field acts as a mediator that enables secure communication and authentication without requiring direct physical connections or additional power sources, resolving the contradiction between security and power consumption
2Ease of operation
If wireless authentication connections are used, then convenience is improved, but security becomes vulnerable to breaches
Solution Approach 1:
The patent applies local quality by restricting NFC authentication to very short ranges (typically less than 10 cm). This localized approach ensures that authentication only occurs when devices are in immediate physical proximity, maintaining convenience while significantly enhancing security compared to wide-area wireless connections
Solution Approach 2:
The patent changes the operational parameters of wireless communication by using NFC's specific electromagnetic frequency and short-range characteristics. This parameter change transforms the security profile of wireless authentication, making it resistant to remote attacks while maintaining ease of operation through contactless proximity-based authentication
3Reliability
If NFC authentication is implemented, then security and efficiency are improved, but device complexity increases
Solution Approach 1:
The patent leverages the universality of NFC technology, which is already integrated into modern smartphones and tablets. By utilizing this existing multi-functional component for authentication purposes, the system achieves enhanced security without adding significant complexity, as the NFC hardware and protocol stack are already present in the devices
Solution Approach 2:
The patent merges the authentication function with the existing NFC communication capability. Instead of adding a separate authentication system, the authentication mechanism is combined with the NFC stack, reducing overall system complexity while improving security and efficiency

AI summary
An apparatus comprises a processing device comprising a near field communication (NFC) network interface, a memory and a processor coupled to a memory. The processing device is configured under control of the processor to connect to a host device using the NFC network interface, receive an authentication request from another device through the NFC connection with the host device and authenticate the other device using information stored in the memory. A passcode is presented to the host device responsive to a successful authentication of the other device, the passcode being utilizable to authenticate to a resource protected by the other device.
