Enhance safety of telecare medicine information system with a RFID-based authentication scheme

Abstract

Medication Safety is an important issue for patients. Telecare medicine information system using RFID technology is used to reduce the medication errors and improve the patient safety. In this paper, we show the weaknesses of Keerti Srivastava et al.'s authentication scheme. In order to enhance medication safety for patients, we propose a new lightweight RFID authentication scheme based on dynamic ID. This scheme only requires O(1) work to identify and authenticate a tag in the backend server, so it is practical, secure and efficient for health care domain.
