Abstract:
A data processing device comprises a storage unit adapted to store an initial value of a pair of a public key and a private key and a communication unit adapted to execute communication with an external device with use of the initial value of the pair of the public key and the private key stored in the storage unit, thereby enabling encryption communication without generating the pair of the public key and the private key.
