摘要
针对文件传输存在的安全性缺陷,提出了一种基于转发模式的双连接文件安全传输方法。采用转发隔离思想设计了双连接结构,对文件存储服务器和客户端进行隔离,通过文件安全传输协议栈实现数据的全程加密和可靠传输,并讨论和解决了双连接结构的数据传输引起的流量控制问题。实验结果表明,基于转发模式的双连接文件安全传输在确保服务器安全性和数据密文传输的同时,保障了文件传输的速度和效率。
Against file transfer security flaws, a dual connection secure file transfer method is proposed based on forwarding model. A dual connection structure is designed by the ideas of forwarding and isolation, which isolates file storage server and client. Full encryption and reliable data transmission is achieved by secure file transfer protocol stack. And a problem of flow control caused by the dual connection structure is discussed and resolved. The experimental results show that secure file transfer method by dual connection based on forward model not only ensures ciphertext transmission and the security of server, but also ensures the speed and efficiency of file transfer.
