A Survey of RFID Authentication Protocols Based on Hash-Chain Method

TL;DR

This survey reviews RFID authentication protocols using hash-chain methods, highlighting their focus areas, limitations, and the need for integrated security solutions in RFID systems.

Contribution

It provides a comprehensive analysis of existing hash-chain based RFID authentication protocols, identifying gaps and limitations in current approaches.

Findings

Protocols improve RFID security and privacy but lack integration.

Most protocols focus on specific security aspects, not comprehensive solutions.

Identifies need for unified RFID authentication frameworks.

Abstract

Security and privacy are the inherent problems in RFID communications. There are several protocols have been proposed to overcome those problems. Hash chain is commonly employed by the protocols to improve security and privacy for RFID authentication. Although the protocols able to provide specific solution for RFID security and privacy problems, they fail to provide integrated solution. This article is a survey to closely observe those protocols in terms of its focus and limitations.
