| 摘 要： | U盘的普及使U盘病毒繁衍迅速，针对信息系统安全保护的需要，设计出一种U盘病毒隔离器。该隔离器具有隔离Autorun病毒、防止PC的数据通过U盘泄密、防止PC中的病毒感染U盘的功能。隔离器能够快速捕获到U盘与主机之间所有底层数据，在此基础上，隔离器中的微控制器(MCU)通过分析、审计和过滤流过隔离器中的底层数据来实现上述功能。经实际检测，该设计能够实现上述功能。

| Abstract: | The popularization of U disk makes virus from U disk spread fast. In order to protect the safety of information system, the authors designed a U disk virus isolator with three functions, firstly isolating Autorun virus from U disk, secondly preventing the PCs data from stealing by U disk, and thirdly preventing the PCs virus from spreading to U disk. The isolator can quickly capture all the data between the U disk and the PC, then the Micro Controller Unit (MCU) of the isolator analyzed, filtered and audited the data transport between U disk and computer to implement those three functions described above. Through actual measuring, it is found that this design can implement those three functions successfully. |
