[0054] The message is a read request message, the file name is opfile, the transmission mode is octet, the user name is admin, and the password is admin.

[0055] Please refer to figure 2 , figure 2 It is a schematic flow chart of the file transfer method using the optional security authentication mechanism of the present invention, assuming that the client is the data sender, the server is the data receiver, and the first authentication information is the user name and password of the client, and the file transfer method includes the following steps :

[0056] In step 201, the client sends a write request message to the server, and the write request message carries a user name and password through a newly added TFTP option. At the same time, the write request message also carries the file transfer mode.

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, the FTP (File Transfer Protocol, file transfer protocol) protocol based on the TCP (Transmission Control Protocol, transmission control protocol) protocol, the HTTP (HyperText Transfer Protocol, hypertext transfer protocol) protocol or the UDP ( The TFTP protocol of the User 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,...
