In order to provide enhanced medication safety for inpatients, the medical mechanism which adopts the modified grouping proof protocol is proposed in this paper. By using the grouping proof protocol, the medical staffs could confirm the authentication and integrity of a group of Radio-Frequency Identification (RFID) tags which are embedded on inpatient bracelets and the containers of drugs. This mechanism is designed to be compatible with EPCglobal Class-1 Generation-2 standard which is the most popular specification of RFID tags. Due to the light-weight computational capacity of passive tags, only the pseudo-random number generator (PRNG) and cyclic redundancy code (CRC) are allowed to be used in the communication protocol. Furthermore, a practical scenario of using this proposed mechanism in hospital to examine the medication safety is also presented.
为了提高住院患者的用药安全性，本文提出了一种采用改进分组证明协议的医疗机制。通过使用分组证明协议，医护人员可以确认佩戴在住院患者手环上的一组射频识别（RFID）标签和药品容器的身份验证和完整性。该机制设计与 EPCglobal Class-1 Generation-2 标准兼容，该标准是 RFID 标签最流行的规范。由于无源标签的计算能力较轻，通信协议中只允许使用伪随机数生成器（PRNG）和循环冗余码（CRC）。此外，还提出了在医院使用该机制检查用药安全性的实际方案。
