A wireless communication system includes a server, in communication with a vehicle controller. The server, in response to receiving from the controller a software update request including a timestamp, identifies a long key associated with the vehicle, encrypts the update beginning at a key offset into the long key generated from a manipulation of a data ordering of the timestamp, and transmits the encrypted update to the controller. A controller, in communication with a server, in response to receiving from the server an encrypted software update triggered by an update request transmitted by the controller and including a timestamp, identifies a long key associated with the vehicle, decrypts the update beginning at a key offset into the long key generated from a manipulation of data ordering of the timestamp, and initiates an installation of the decrypted update on the vehicle.
