A Post-Quantum Secure RFID Authentication Protocol Based on NTRU Encryption Algorithm.

Area of Science:

• Cryptography and Network Security
• Internet of Things (IoT) Security
• Post-Quantum Cryptography

Background:

• Radio Frequency Identification (RFID) systems face significant security and privacy vulnerabilities due to open communication links.
• Existing RFID authentication protocols often lack key management flexibility and scalability, hindering large-scale deployments.
• Public key cryptography presents a viable solution, with NTRU emerging as a promising post-quantum candidate.

Purpose of the Study:

• To propose a novel mutual authentication protocol for RFID systems leveraging the NTRU encryption algorithm.
• To address the security and privacy concerns inherent in current RFID authentication methods.
• To evaluate the protocol's security and performance, particularly in the context of post-quantum cryptography.

Main Methods:

• Development of a mutual authentication protocol based on the NTRU encryption algorithm.
• Security analysis using BAN-logic tools and non-formalized methods.
• Protocol validation through simulation using the AVISPA tool.

Main Results:

• The proposed NTRU-based RFID authentication protocol offers enhanced security and privacy.
• With specific parameters (N=443, p=3, q=2048), NTRU provides 128-bit post-quantum security strength.
• The protocol demonstrates competitive advantages in energy consumption and computation time compared to traditional algorithms like ECC.

Conclusions:

• The NTRU encryption algorithm is a strong candidate for securing large-scale RFID deployments against future quantum threats.
• The proposed protocol effectively mitigates security flaws found in previous NTRU-based RFID authentication attempts.
• This research contributes a practical and secure post-quantum solution for RFID systems.
