Amanuma holds a patent for an innovative authentication system. This system includes a vehicle onboard ECU, an update tool for vehicle control software, and an authentication server for the update tool. The update tool substitutes a predetermined constant and a first random number into a predetermined function to generate a first value, which is then sent to the authentication server. The server signs this first value using a secret key and sends it back to the update tool. Upon connection, the update tool transmits the first value and its signature to the ECU. The ECU verifies the signature using a public key and generates a second value. The update tool then uses this second value and the first random number to create a third value.
