Abstract
The present disclosure relates to a data processing device, a data processing method, and a program for enabling safe transmission of biometric authentication results between chips. A first chip and a second chip perform encryption and decryption using a first common key, and hold a first counter value. The first chip encrypts a command and the first counter value, and transmits the command and the first counter value to the second chip. The second chip encrypts an execution result of the decrypted command and the second counter value, and transmits the encrypted execution result and second counter value to the first chip. The first chip and the second chip synchronize the first counter value and the second counter value, each time transmitting/receiving data to/from each other. The technology according to the present disclosure can be applied to a fingerprint authentication device, for example.
