Summary: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.
