Embodiment Construction
[0020] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0021] Such as figure 1 As shown, the implementation steps of the simple identity verification method used in the file transfer protocol in this embodiment are as follows:
[0022] 1) Both the client and the server preset the authentication encryption algorithm related to the client information;
[0023] 2) The client generates an authentication string through the authentication encryption algorithm combined with its own information and sends it to the server through the FTP protocol;
[0024] 3) The server receives the FTP protocol request from the client and the authentication string sent by the client, and generates the target authentication ...

The invention discloses a simple identity authentication method for a file transfer protocol (FTP). The simple identity authentication method comprises the implementation steps as follows: 1) identity authentication encryption algorithms are simultaneously preset on a client-side and a server; 2) the client-side generates an identity authentication character string and sends the identity authentication character string to the server through the FTP; 3) the server receives an FTP request of the client-side and the identity authentication character string sent by the client-side, and generates a target authentication character string; and 4) the server compares the identity authentication character string with the target authentication character string, if the identity authentication character string is the same as the target authentication character string, the server returns an FTP answer-back code 230 to the client-side, and if the identity authentication character string is different from the target authentication character string, the server returns an FTP answer-back code 503 to the client-side. The simple identity authentication method has the advantages that simple identity authentication of the FTP can be realized, the compatibility of a browser is good, the authentication is simple and reliable, and the use is convenient.
Description
technical field [0001] The invention relates to the field of computer communication, in particular to a simple authentication method for file transfer protocols. Background technique [0002] FTP protocol (File Transfer Protocol) is a remote file transfer protocol. It is a protocol used to simplify file transfer between systems on an IP network. FTP is a specific application of TCP / IP. It works on the seventh layer of the OSI model. On the fourth layer of the TCP model, that is, the application layer, TCP is used for transmission instead of UDP, and FTP establishes a reliable connection. The use of the FTP protocol can enable Internet users to efficiently download data files with a large amount of information from the FTP server on the Internet, and copy the files on the remote host to their own computers. In order to achieve the purpose of resource sharing and transmission of information. Due to the use of FTP, a large number of download services for users appear on the I...
