Security Analysis and Enhancement of the Most Recent RFID Protocol for Telecare Medicine Information System

Radio-frequency Identification (RFID) schemes have been widely adopted in medical healthcare environments such as telecare medicine information system (TMIS). There are many research focus in the privacy protection of medical information security with cloud computing and big data technologies. This paper deeply identified the attacks of two RFID protocols in the literature. Fan et al.’s protocol (LRMP) and Benssalah et al.’s scheme (TMISP) both are subjected to tracking attacks, tag impersonation attacks, reader impersonation attacks. LRMP protocol suffers from de-synchronization attacks. In order to solve main weaknesses, the article presents a RFID medical privacy protection scheme based on cloud computing. The scheme ensures security and privacy of the collected data via secure authentication. The security analysis and performance evaluation shows that the proposed scheme can effectively solve security and privacy weaknesses, and resist against forward traceable attacks and backward traceable attacks.
