Abstract
With the fast advancement of the wireless communication technology and the widespread use of medical systems the radio frequency identification RFID technology has been widely used in healthcare environments As the first important protocol for ensuring secure communication in healthcare environment the RFID authentication protocols derive more and more attentions Most of RFID authentication protocols are based on hash function or symmetric cryptography To get more security properties elliptic curve cryptosystem ECC has been used in the design of RFID authentication protocol Recently Liao and Hsiao proposed a new RFID authentication protocol using ECC and claimed their protocol could withstand various attacks In this paper we will show that their protocol suffers from the key compromise problem ie an adversary could get the private key stored in the tag To enhance the security we propose a new RFID authentication protocol using ECC Detailed analysis shows the proposed protocol not only could overcome weaknesses in Liao and Hsiao’s protocol but also has the same performance Therefore it is more suitable for healthcare environmentsThe authors thank Prof Jesse Ehrenfeld and anonymous reviewers for their valuable comments This study was supported by the International ST Cooperation Program from the Ministry of Science and Technology of China No 2012DFA91530 the “Twelfth 5yearplan” Support Plan Projects No 2011BAD25B01 the introduction of highlevel Talents Foundation of North China University of Water Resources and Electric Power No NCWU201248 and the Key Technique Program of the Education Department of Henan Province 13A570704
