An improved NFC device authentication protocol

Area of Science:

• Cybersecurity
• Cryptography
• Wireless Communication

Background:

• Near Field Communication (NFC) devices face significant security authentication challenges.
• Existing NFC protocols are vulnerable to various attacks, compromising data confidentiality and integrity.
• The need for robust security measures in NFC is critical for widespread adoption and secure transactions.

Purpose of the Study:

• To address the security authentication problems in Near Field Communication (NFC) device interactions.
• To enhance the confidentiality, performance, and overall security of NFC authentication protocols.
• To develop a protocol resistant to common cyber threats like brute force, man-in-the-middle, and replay attacks.

Main Methods:

• Utilized a combination of asymmetric and symmetric encryption algorithms.
• Incorporated hash functions, timestamps, and survival periods into the authentication process.
• Implemented symmetric encryption for transmission content and asymmetric encryption for shared keys.

Main Results:

• Achieved secure authentication and secure key distribution between NFC devices.
• Demonstrated effective resistance against brute force, man-in-the-middle, and replay attacks.
• Reduced message transmission count, improving overall transmission efficiency.

Conclusions:

• The improved NFC device authentication protocol significantly enhances security.
• The protocol boosts confidentiality, integrity, and non-repudiation in NFC communications.
• This enhanced protocol offers a more secure and efficient solution for NFC device authentication.
