基于CH374的一种安全的文件写入器的研制

Research and Implement on a Safe File Writer Based on CH374

用ATMEGE64、CH374芯片为核心,开发了一套连接到个人计算机USB端口的安全的文件写入器。该系统不仅通过硬件设计杜绝木马从USB设备入侵个人计算机,还利用文件混沌加密方法确保用户文件的信息安全,系统结构简明,使用方便,传输快捷,经客户验证其有效性。文章介绍了该系统硬件结构、驱动程序、界面程序的设计思路和实现方法。

In this paper, we use ATMEGE64 and CH374 as kernel to realize a file writer connected with USB port of PC. This system not only can prevent virus from intruding PC by USB port, but also guarantee users＇ information safety by protecting their files with chaos eneryption method. What＇s more, the system has a simple construction, high writing speed for user convenience. We introduce the hardware structure, driver and interface program in detail.
