The present invention relates to a system and method for distributing files, such as data files, executable files, and web page content files, between an unsecure server and a client. The client is capable of authenticating the transferred file to determine if the creator of the file has been previously authorized to create files for the client. The file creator may be the original equipment manufacturer (OEM) of the client. The file creator may be a third party that is not the same party as the OEM of the client.
