Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RFID authentication systems do not allow for different levels of user authentication protocols based on varying security levels associated with soft and hard assets, necessitating a self-contained, hardware-based secure access methodology.
Innovation Solution
A RFID authentication system utilizing dual RFID tags operating on different frequencies, where one tag transmits an encrypted identifier over a public frequency and the other tag transmits a private key over a private frequency, allowing for multiple levels of user authentication based on determined security levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single RFID tag operating on a public frequency is used for authentication, then the system is simple and easy to operate, but it cannot provide different levels of user authentication protocols based on different security levels
Solution Approach 1:
The authentication system is segmented into multiple RFID tags operating on different frequencies. The first RFID tag operates on a public frequency for basic authentication, while the second RFID tag operates on a private frequency for enhanced security. This segmentation allows the system to provide different levels of authentication protocols based on security requirements without requiring complete system redesign.
Solution Approach 2:
The RFID system is designed with multi-functionality to handle both public and private frequency operations. The system can universally support both basic authentication (using public frequency tag) and enhanced authentication (using private frequency tag), making it adaptable to various security level requirements while maintaining a unified authentication framework.
2Reliability
If dual RFID tags operating on different frequencies are used, then different authentication protocols for different security levels are enabled, but the device complexity increases
Solution Approach 1:
Security functionality is segmented across two RFID tags with different frequency capabilities. The public frequency tag handles basic authentication scenarios, while the private frequency tag handles high-security scenarios. This segmentation improves reliability by ensuring that security-critical operations use the more secure private frequency channel, while maintaining operational simplicity for low-security operations.
Solution Approach 2:
Different security levels are applied locally to different authentication scenarios. The system uses public frequency authentication for low-security local operations and private frequency authentication for high-security local operations. This local quality approach ensures that complexity is only introduced where security requirements demand it, rather than uniformly across all operations.
3Adaptability or versatility
If manual user authentication protocols and single-frequency RFID tags are used, then the system is easy to operate, but it lacks flexibility for varying security levels of assets
Solution Approach 1:
The RFID authentication system operates automatically without requiring manual intervention. The appropriate authentication protocol (public or private frequency) is self-selected by the system based on the security level of the asset being accessed. This self-service capability maintains ease of operation while providing adaptability to different security requirements, as users simply present their RFID tag and the system handles the complexity of protocol selection.

Function Achieved in This Case
Enables secure access to assets with varying security levels by instituting appropriate authentication protocols, enhancing security and flexibility in user access control.
Implementation Method 1
The RFID reader antenna transmits a radio frequency signal to activate and, thereby initiate transmission of the authentication information by the RFID tag antenna
Implementation Method 2
The RFID reader antenna further receives (i.e., reads) the transmitted authentication information

AI summary
Disclosed is a self-contained hardware-based authentication system that incorporates different authentication protocols for access to soft and/or hard assets with different security levels. The system embodiments include the use of a RFID device that comprises dual RFID tags operating under different frequencies. Specifically, one RFID tag operates on a public frequency and, when activated, transmits an identifier encrypted using a public key. The other RFID tag operates on a private frequency and, when activated, transmits a private key that can be used to decrypt the encrypted identifier. Upon receipt by a processor (e.g., a local processor or security server) of a request for access to a specific asset, a security level for the specific asset is determined. Then, depending upon the particular security level (e.g., low, medium or high) different authentication protocols are instituted using the RFID device. Also disclosed are embodiments of an associated authentication methodology.
