近年來IoT的發展應用越來越貼近我們的日常生活，根據研究 顯示未來 IoT 的使用，在醫療照護上的經濟影響將佔 IoT 應用整 體的四成，在整體比例為最高，顯示出 IoT 在醫療照護上的潛 力。在醫療照護應用上，常需傳送病人的身體狀況等個人隱 私，若 IoT 感測器遭到攻擊或傳送的資訊被竊取，將會造成個人 的權益受損，因此一個良好的 IoT 無線感測網路遠端認證機制其 必要性，本研究在 Wu 與 Xu 等人以及 Wu 與 Li 等人提出的認證 機制進行安全性分析，發現其機制的匿名性及取得感測器攻擊的 安全性不夠完善，於本文中提出其機制存在的漏洞，並提出新的 IoT 無線感測網路遠端認證機制，以具有更佳的安全性及未來實 用的價值。
Recently, the development and application of Internet of Thing (IoT) have more and more close to our daily life. According to research, in the future, the use of IoT will account for 40% of the IoT application in health care, showing the potential of IoT. In health care applications, it is often to transmit private data such as the patients physical condition. If the attacker hacks the IoT sensor or stoles the transmitted information, it will violate the legitimate rights. So, a secure IoT wireless sensor network (WSN) remote authentication scheme is necessary. In specific, this study finds the authentication schemes proposed by Wu et al. (2017, 2018) do not provide anonymity protection and the security of the sensor. In this paper, we not only point out the weakness of Wu et al.s schemes (2017, 2018) but also proposes a new IoT WSN remote authentication mechanism for better security and future practical value.
