Embodiment 1

[0050] See figure 1 , the file downloading system in this example includes a network management system and an equipment system, wherein the network management system includes a file acquisition device, an encryption device, and a file sending device; the file acquisition device is used to get the original file, it is worth noting that the The original file refers to an unencrypted file. For example, if the network management system obtains a version file, the original file here refers to an unencrypted version file; the encryption device is used to obtain the original file obtained by the file acquisition device. The file is encrypted to obtain an encrypted file and corresponding encryption parameters; the file sending device is used to send the encrypted file obtained from the encryption device to the equipment system through the file transmission link, and send the encryption parameters obtained from the encryption device to the device through a secure link system; the file ...

Embodiment 2

[0083] In order to better understand the present invention, this example takes a specific implementation process as an example to further describe the present invention. The file downloaded by the device system in this example is a version file, that is, the original file obtained by the network management system in this example is an unencrypted version file, and the file transmission between the network management system and the device system in this example is carried out using the FIP protocol. Please refer to the specific implementation process image 3 :

[0084] Step 0, the network management system receives the version download instruction;

[0085] Step 1, the network management system obtains the version file that needs to be downloaded through the file acquisition device, which is denoted as F0; the step of obtaining the version file is not the focus of the present invention, so it will not be repeated here;

[0086] Step 2, the network management system randomly ...

Abstract

The present invention relates to the field of communications. Disclosed are a method and an apparatus for downloading a file. In the present invention, a network management system acquires an original file and encrypts the acquired original file to obtain an encrypted file and a corresponding encryption parameter; sends the obtained encrypted file to a device system through a file transfer link and sends the obtained encryption parameter to the device system through a secure link. Upon acquiring the encrypted file and the encryption parameter through the different paths, the device system decrypts the encrypted file according to the encryption parameter to obtain the original file, thereby improving the efficiency and security of file transmission.

Description

technical field [0001] The invention relates to the communication field, in particular to a file downloading method and system. Background technique [0002] In the communication network management, the file transfer protocol (FTP protocol: File Transfer Protocol) is widely used because of its fast transmission speed and high efficiency. Like most Internet services, FTP is also a client / server system. Users connect through a client program to a server program running on a remote computer. The computer that provides services according to the FTP protocol and transfers files is the FTP server, and the computer that connects to the FTP server and transfers files with the server according to the FTP protocol is the FTP client. [0003] With the advancement of technology, operators have higher and higher security requirements for network management. Although the transmission efficiency of the FTP protocol is high, its security is very low, so protocols such as SFTP (Secure FTP...
