Improvement of the security of communication is facilitated. A server receives from an on-vehicle device, encrypted data obtained by encrypting ECU information using key information (111-1#C), and identification information (112-1#C). Thereafter, the server determines from the identification information (112-1#C), whether identification information of a next key to be used after identification information (112-1) is stored. The server determines that the identification information of the next key to be used after the identification information (112-1) is not stored, and obtains key information (111-2#S) and identification information (112-2#S) to identify key information (111-2) as the next key. The server encrypts the key information (111-2#S) and the identification information (112-2#S) using key information (111-1#S), and transmits encrypted data and identification information (112-1#S) to the on-vehicle device.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
