Abstract

The invention provides a file transmission method, a system, a client and a server based on a trivial file transfer protocol (TFTP). The file transmission method comprises the following steps that: a client sends a first authentication information to a server so that the server performs authentication to the client; when the authentication to the client from the server passes, file data transmission can be performed between the client and the server. By using the method, the system, the client and the server, security of a TFTP transmission system can be raised.

Description

technical field

[0001] The present invention relates to the communication field, in particular to a file transfer method, system, client and server based on TFTP (Trivial File Transfer Protocol, simple file transfer protocol). Background technique

[0002] In the wired communication system, usually use FTP (File Transfer Protocol, file transfer protocol) agreement based on TCP (Transmission Control Protocol, transmission control protocol), HTTP (HyperTextTransfer Protocol, hypertext transfer protocol) agreement or use UDP (User The TFTP protocol of the Datagram Protocol (User Datagram Protocol) protocol realizes the transmission of file data.

[0003] The transmission based on the FTP protocol and the HTTP protocol has a connection state, so the transmission is more reliable, but it takes up more system resources. However, the transmission based on the TFTP protocol has no connection state, so it occupies less system resources, but it has no security certification, and it i...
