Medication error can easily cause serious health damage to inpatients in hospital. Consequently, the whole society has to spend huge amount of extra resources for additional therapies and medication on those affected inpatients. In order to prevent medication errors, secure inpatient medication administration system is required in a hospital. Using RFID technology, such administration system provides automated medication verification for inpatient's medicine doses and generates corresponding medication evidence, which may be audited later for medical dispute. Recently, Peris-Lopez et al. (Int. J. Med. Inform., 2011) proposed an IS-RFID system to enhance inpatient medication safety. Nevertheless, IS-RFID system does not detect the denial of proof attack efficiently and the generated medication evidence cannot defend against counterfeit evidence generated from the hospital. That is, the hospital possesses enough privilege from the design of IS-RFID system to modify generated medication evidence whenever it is necessary. Hence, we design two lightweight RFID-based solutions for secure inpatient medication administration, one for online verification environment and the other for offline validation situation, to achieve system security on evidence generation and provide early detection on denial of proof attack.
用药错误很容易对住院患者造成严重的健康损害。因此，全社会不得不为受影响的住院患者额外支付大量额外的治疗和用药费用。为了防止用药错误，医院需要安全的住院用药管理系统。使用 RFID 技术，这种管理系统可为住院患者的药物剂量提供自动用药验证，并生成相应的用药证据，以备日后医疗纠纷进行审核。最近，Peris-Lopez 等人（Int. J. Med. Inform.，2011）提出了一个 IS-RFID 系统，以提高住院患者用药安全性。然而，IS-RFID 系统不能有效地检测到证据否认攻击，并且生成的用药证据不能抵御来自医院的伪造证据。也就是说，医院从 IS-RFID 系统的设计中拥有足够的特权，以便在必要时修改生成的用药证据。因此，我们设计了两种基于轻量级 RFID 的安全住院用药管理解决方案，一种用于在线验证环境，另一种用于离线验证情况，以实现证据生成的系统安全性，并对证据否认攻击进行早期检测。
