隨著科技的進步，隨身碟輕薄短小易於攜帶；遵循著摩爾定律及NAND Flash製程技術的提昇，使得記憶體容量不斷的增加，市面上主流販售的隨身碟更是每提升新台幣一百元容量就呈倍數成長。因此，隨身碟早已成為日常存放資料的重要工具。然而；隨身碟本身卻具有嚴重的資安問題，尤其當隨身碟應用在商業用途時，資料保密的問題更顯重要。有鑑於此，本論文提出高安全性的混沌認證技術，並將此混沌認證技術，應用在高安全性USB隨身碟的設計。首先，本論文將提出離散滑動模式控制器的設計, 使得主僕超混沌Hénon map系統達到廣義同步，其次，將上述同步的結果應用於具混沌認證的高安全性USB隨身碟的設計上。我們分別在微控制器(僕端)和智慧型手機(主端)中；建構離散化主僕超混沌Hénon map系統，透過藍芽裝置進行主端及僕端的傳輸通訊以實現混沌同步及認證。使用者只要輕鬆地開啟安裝於智慧型手機中的加密應用程式(APP)進行混沌認證後，即可存取隨身碟內部資料。

Due to technological advancement, flash drives have become light and easy to carry. Following Moore's Law, improvements in NAND flash process technology have resulted in a continuous increase in memory capacity in flash drives. It has been predicted that the sales of mainstream flash drives in the market will double to NT$100 per unit of capacity. Therefore, the flash drive has become an important device for daily storage of data. However, flash drives have serious security problems, especially when the flash drive is used for commercial purposes. The issue of confidentiality of data is especially important. Therefore, this paper proposes a high-security chaos authentication technology and applies this authentication technology to the design of high-security USB flash drives. First, a design for a a discrete sliding mode controller is proposed, which makes the master-slave hyperchaotic Hénon map system achieve generalized synchronization. Then, the obtained results are applied to the design of a highly secure USB flash drive with chaotic authentication. We build a discrete master-slave hyperchaotic Hénon map system in a microcontroller (slave) and a smart phone (master), respectively, and use a Bluetooth device to transmit and communicate between the master and the slave to achieve chaos synchronization and authentication. The user can easily access the data on flash drives by simply turning on the encrypted application (APP) installed in the smart phone for chaos authentication.
