Abstract

It is a great challenge for researchers to design a lightweight RFID protocol because tags lack sufficient computational resources, memory, power and communication ability. In this paper, we analyze two protocols respectively proposed by Choi et al and Ha et al and find the protocol proposed by Ha et al has security vulnerability. Afterwards, we propose an enhanced HGLAP and analyze its property. The result indicates that the computational load of this protocol does not increase obviously and this protocol can provide mutual authentication, forward secrecy and protect from replay attack, desynchronization attack and tracing attack.
