Abstract
A system and method for updating software for a remote unit over a network is disclosed herein. The system and method includes the remote unit, an authentication server and an update server. The remote unit may have a flasher host for communicating over the network and for transmitting commands to the remote unit. The system and method allows for the verification of a request message from the remote unit, and a response from the authentication server. The response message to the remote unit from the authentication server will contain an decryption key to decrypt the update file that will be sent by the update server. Such an authentication process prevents rogue programs from being sent to the remote unit thereby decreasing the potential for cellular fraud.
