Abstract
A management device installed in an automobile includes an initially-delivered key storage unit for storing a plurality of initially-delivered keys corresponding to candidates of initially-delivered keys held by an ECU, a communication part for communicating with the ECU, a verification part for verifying encrypted data from the ECU with the initially-delivered key of the initially-delivered key storage unit, and a wireless communication part for receiving a new initially-delivered key held by a new ECU newly installed in the automobile from management server equipment through a wireless communication network. The initially-delivered key storage unit stores the new initially-delivered key received with the wireless communication part.
