Enciphering apparatus and method deciphering apparatus and method as well as information processing apparatus and method

Abstract

The invention provides an enciphering apparatus and method a deciphering apparatus and method and an information processing apparatus and method by which illegal copying can be prevented with certainty. Data enciphered by a 1394 interface of a DVD player is transmitted to a personal computer and a magneto-optical disk apparatus through a 1394 bus. In the magneto-optical disk apparatus with which a change to a function is open to a user the received data is deciphered by a 1394 interface. In contrast in the personal computer with which a change to a function is open to a user the enciphered data is deciphered using a time variable key by a 1394 interface and a result of the decipherment is further deciphered using a session key by an application section.
