Abstract
An automobile is equipped with a management device including a communication part for communicating with an ECU mounted on an automobile, an encryption processor for generating an encrypted key by encrypting a key, a key generation part for generating the key, and a key storage unit for storing the key generated by the key generation part. The communication part transmits the encrypted key to the ECU, while the encryption processor encrypts the key generated by the key generation part.
Claims24
A management device installed in a vehicle, comprising:
- a communication part configured to communicate with an on-board computer mounted on the vehicle;
- an encryption processor configured to encrypt a key and thereby generate an encrypted key;
- a key generation part configured to generate the key;
- and
- a key storage unit configured to store the key,
- wherein the communication part transmits the encrypted key to the on-board computer mounted on the vehicle, and
- wherein the encryption processor encrypts the key.
A key generation device comprising a key storage unit configured to store a master key, wherein a key generated using the master key is supplied to an on-board computer mounted on a vehicle.
A management method comprising:
- a communication step for allowing a management device installed in a vehicle to communicate with an on-board computer mounted on the vehicle;
- an encryption processing step for generating an encrypted key by encrypting a key with the management device;
- a key generating step for generating the key with the management device;
- and
- a key storing step for storing the key having being generated with the management device,
- wherein the management device transmits the encrypted key to the on-board computer mounted on the vehicle, and
- wherein the management device encrypts the key having being generated.
A management method comprising:
- a key storing step for storing a master key with a key generation device;
- and
- a key supplying step for supplying a key, which is generated using the master key, to an on-board computer mounted on a vehicle.
A non-transitory computer-readable storage medium having stored a program causing a computer mounted on a vehicle to implement:
- a communication step for communicating with an on-board computer mounted on the vehicle;
- an encryption processing step for generating an encrypted key by encrypting a key;
- a key generating step for generating the key;
- and
- a key storing step for storing the key having been generated,
- wherein the encrypted key is transmitted to the on-board computer mounted on the vehicle in the communication step, and
- wherein the key having been generated is encrypted in the encryption processing step.
A non-transitory computer-readable storage medium having stored a program causing a computer mounted on a key generation device to implement:
- a key storing step for storing a master key;
- and
- a key supplying step for supplying a key, which is generated using the master key, to an on-board computer mounted on a vehicle.
