Medication Safety is an important issue for patients. Automated patient medication system using RFID technology is used to reduce the medication errors and improve the patient safety. In this paper, we show the weaknesses of Sonam Devgan Kaul 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 and is particularly suitable for the low-cost RFID systems because only one-way hash function, XOR operation and concatenation operation are needed in tag part, so it is practical, secure and efficient for health care domain.
