Abstract
The present disclosure relates to a method of managing a controller with reliability and, more particularly, to authentication and data exchange during installation/use/removal of a vehicle controller, a gateway and a tester using an encryption algorithm. A method of authenticating a controller by a gateway in a vehicle includes: transmitting a first message including a first random number to the controller when a first condition is satisfied; receiving, from the controller, a second message including the first random number to which an electronic signature has been attached through a private key of the controller; decrypting the first random number having the electronic signature attached thereto using a public key of the controller; and transmitting, to the controller, a symmetric key encrypted using the public key of the controller when the decryption has been successfully performed.
