摘　　要：通过修改UDP通信协议,结合光传播的不可逆性,首次实现了安全单向信息传输系统,防止USB设备向目标主机进行文件传输时,盗取目标主机中的资料。系统硬件方面采用了S3C2410芯片(ARM920T内核)、光发送器、光接收器、多模单向光纤以及USB控制芯片等,软件方面设计了自定义UDP通信协议实现ARM芯片上的uCLinux系统向计算机系统传输数据,阐述了自定义UDP通信协议的结构、注释、规则。该系统结合嵌入式USB通信设备和自定义UDP通信协议,不仅传输效率达到2M以上,而且实现传输的单向性、可靠性。A one-way information transmission system has been implemented for the first time by modifying the UDP communication protocol and integrating the irreversibility of optical transmission,which can prevent file stolen from target host when USB device transferring files with the target host.System＇s hardware included S3C2410 chip（ARM920T core）,optical transmitter,optical receiver,one-way multi-mode optical fiber and USB controller chips,while system＇s software was designed a customized UDP communication protocol to achieve data transmission between computer system and ARM-based uclinux system.It also described the structure,annotation and rule of the customized UDP communication protocol.The system combined embedded USB communication device and customized UDP communication protocol,achieved the transmission efficiency higher than 2M,as well as a one-way and reliable transmission.
