The flash package file is a BIN file provided by a manufacturer and written with a Seedkey algorithm.
The remote platform server performs real-time verification on the flash package file and the secret key file stored in the remote monitoring terminal through a remote access server group, and the method specifically comprises the following processes: the remote monitoring terminal loads the BIN file to the memory of the remote monitoring terminal, and in the flashing process, the algorithm is used for encrypting the Seed value sent by the flashed ECU and then sending the Seed value back to the flashed ECU, so that the remote monitoring terminal passes the identity authentication of the ECU.
The remote control terminal adopts mobile intelligent equipment.
In the swiping process, if the SD card of the remote monitoring terminal is pulled out and then inserted, the remote monitoring terminal stops swiping, the remote platform server conducts real-time verification on a swiping package file and a secret key file stored in the remote monitoring terminal through a remote access server group, meanwhile, the state of the vehicle to be swiped is monitored in real time through the remote monitoring terminal, and if the swiping package file and the secret key file are confirmed to be in consistency with original file information stored in the remote platform server through verification and the vehicle to be swiped is in a non-running state, the remote monitoring terminal sends swiping ready state information to the remote platform server and the remote control terminal through the remote access server group; and then the remote control terminal sends a flash control instruction to the remote monitoring terminal through the remote access server group, so that the remote control terminal can continuously flash the vehicle to be flashed by using the flash packet file.
