| 摘 要： | 随着科学技术的发展，U盘作为一种大容量存储设备，已成为人们移动存储的首选。然而在U盘发挥着越来越重要作用的同时，其数据安全问题也日益突出。为了提高U盘安全性，防止重要数据被他人窃取或篡改，设计并实现了一种双钥模式加密U盘。采用双钥模式，可以支持指纹和PIN码解锁U盘中存储的数据。使用INIC3861主控芯片对存储芯片中的数据进行硬件加密，结合指纹管理软件，可实现对用户身份的唯一认证以及数据安全性管理。同时设计了身份绑定认证机制，以保障各模块之间的通信安全，从而实现了对数据加密密钥的保护。

| Abstract: | With the development of science and technology， U disk as a mass storage device has become the first choice of people's mobile storage devices. However， as it plays an increasingly important role， the impact of its data security issues are also increasing. In order to improve the security performance of USB disk and prevent someone from stealing or tampering important data， an double secret key mode security USB disk is proposed and implemented in this paper. The fingerprint and PIN code are used as double key to unlock the data stored in the USB disk. The data of memory chip is encrypted with hardware security engine from INIC3861 controller. The unique authentication of the user identity and the security management of the data are achieved by combining fingerprint management software and INIC3861 controller. And the identity binding authentication mechanism is designed to ensure the communication security between the modules and achieve the protection of the data encryption key. |
