ABSTRACT:
The present invention discloses a method for preventing a control program written in a first engine control unit (ECU) from running in a second ECU, comprising obtaining an ID number from the first ECU; encrypting the ID number; writing the encrypted ID number into a flash memory of the first ECU; encrypting the ID number again and writing the encrypted ID number into an EEPROM of the first ECU; and requiring the control program to match the encrypted ID number placed in the flash memory and the EEPROM before running the program, and if the match fails, terminating the control program from running further.
