近年來物聯網裝置普及，各類型的裝置結合各種感測元件形成許多不同類型的新興應用。智慧城市、智慧醫療、智慧家庭皆被廣泛討論。物聯網的應用從環境訊號感測開始，將收集來的資料進行處理，最後會回傳這些資料至伺服器端。隨著物聯網的發展，與人身安全、公共安全相關的裝置會大量且快速增加，因此隱私方面則比過去更加被重視。由於涉及的層面價值提升，因此需要針對物聯網裝置的硬體安全機制進行建立與增進。
本論文提出一針對輕量級微系統之硬體安全性探勘之設計平台，此平台以電子系統層級的概念建置，於微系統中提出可靠且低耗能之安全機制。此平台包含安全管理元件，透過安全管理元件以及物理不可複製函數(PUF)提供之金鑰將安全機制在微系統中執行。此外，此平台具有很大的模擬彈性與擴充性，其中之安全管理元件幫助安全管理機制設計者於早期設計階段進行硬體安全性機制之規畫以及額外能量消耗之評估。

Nowadays, Internet of Thing (IoT) devices become popular; many different kinds of devices combining with sensors form a brand new application. Smart city, smart medical and smart house are all widely adopting. The IoT device starts from environmental signal sensing, processes the collected data and transmits the data to gateways or servers. As the IoT development, the number of devices related to human privacy and public safety is increasing in large quantity, so that the security issue of IoT devices becomes more important than ever. Reliable hardware secure methodologies are urgently required.

In this work, we propose a design exploration platform for a lightweight hardware secure microsystem at electronic system level. Furthermore, we propose a reliable and low-energy consumption security mechanism on the microsystem platform. The platform has a secure management unit that can execute reliable security mechanism using PUF keys. In addition, the platform provides flexibility and extensibility that allow the designers to develop hardware security mechanism and evaluate the energy consumption issue for exploration.
