基于嵌入式Linux下安全文件传输系统的设计

为了在Linux终端设备间安全地传输网络数据，设计了一种基于嵌入式Linux的安全文件传输系统。在SSL（Secure Socket Layer）协议加密方法的基础上，给出了系统软件服务端和客户端设计流程并对系统的安全性进行了分析。服务端和客户端文件在传输过程中通过SSL协议加密，服务端采用多线程允许多个客户端接入。结果表明，该系统有利于网络数据传输安全问题的解决，促进了移动互联网中网络安全的发展。

Design of Secure File Transfer System Based on Embedded Linux

In order to transmit network datas safely among terminal devices,the design of secure file transfer system based on embedded Linux is introduced.The architecture of secure file transfer system is introduced,the way of designing system software of server and client is explained based on SSL(Secure Socket Layer)protocol,and system security is analyzed.The file between server and client is encrypted through the ssl protocol during the transportation,and the server is connected by several clients because of multi-threading.The design can help solve the problems in transmitting network datas safely and facilitate to develop network security in the mobile internet.
