Security application system suitable for common U disks

Abstract

The invention discloses a security application system suitable for common U disks and belongs to the field of application systems. A U disc flash storage area consists of a cdrom storage area, a disk storage area and a log area; the initial manifestation patters of the areas are read only; the cdrom storage area is used for storing read-only application programs; the log area is used for storing log files; the security application system is capable of realizing the switching from a disk storage area cdrom state to a disk stage through a USB protocol; through a bottom driving service, the U disk only can be accessed by a specific progress; and by utilizing a HOOK, the real-time operation of a service U disk file is monitored and recorded in the log area. Compared with the prior art, the security application system suitable for common U disks has the advantage of integrating the technologies such as the USB protocol, the driving service and the HOOK, so that the common U disks without encryption functions are capable of realizing high security access mechanisms under constructed operation environments.
本发明公开了一种适用于普通U盘的安全应用系统,属于应用系统领域。所述U盘flash存储区由cdrom存储区,磁盘存储区和日志区组成,各区初始的表现形式均为只读,其中,cdrom存储区用于存放只读应用程序,日志区用于存放日志文件;安全应用系统通过USB协议实现磁盘存储区cdrom状态到磁盘状态的切换;通过底层驱动服务保证U盘只能被特定的进程访问;利用HOOK监控服务U盘文件的实时操作,并记录在日志区中。与现有技术相比,本发明的适用于普通U盘的安全应用系统集成了USB协议、驱动服务和HOOK等技术,可以使不具备加密功能的普通U盘,在构建起来的操作环境下实现很高的安全访问机制。
