基于PNP自动映射分区的安全USB技术研究与实现

Research and implementation of USB technology based on PNP automatic mapping local

目前多数安全USB设备使用时,需要开启一个应用程序界面来对USB设备进行读写、加密/解密。对此,提出并实现了一种利用硬件PNP技术自动对USB映射为本地盘符,拔下时自动删除盘符的技术。读写文件时,对USB设备自动透明加解密;安全U盘使用前经过授权中心统一注册与授权,划分为权限注册区和加密区;用户密码验证采用基于密码的密码系统说明书(RFC2898)和应用伪随机函数导出密钥(PBKDF2);权限管理采用预先设定好的内、外网策略,内网策略分为多个等级。在实际应用中取得了较好效果。

Now most secure USB device need to open an application GUI to read, write, encryption and decryption. This paper implements a proposed use of the USB hardware PNP technology automatically mount the local drive letter, automatically dismount the drive letter when plug off. Read and write files on the USB device automatically transparent encryption and decryption. USB disk must use the security center before the authorized unified registration and licensing, registration area is divided into permissions and encryption area. User password authentication using password-based cryptography manual （RFC2898） and pseudo-random function to export the key application （PBKDF2）. Rights management using pre-configured within the network outside the network strategy is divided into multiple levels within the network strategy, in practice achieved better results.
