Contents data that have been enciphered and transmitted are recorded as they are on a recording medium, and the contents key used to encipher these data is enciphered in a way used in this recording system and is recorded on the medium. Moreover, a step is taken to ensure that fine trick plays can be performed. In recording contents data that have been enciphered and transmitted, the contents data themselves are recorded in the enciphered state on the recording medium. However, the contents data are decoded by a contents data decoding circuit, and a map file containing necessary management information for reproduction is created by a map file creating circuitand this file is recorded together with the contents data.

Information recording and/or reproducing apparatus

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.

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

A security module is provided in a data recording medium, data to be written to the data recording medium is encrypted with an content key different from one data to another, and the content key is safely stored in the security module. Also, the security module makes a mutual authentication using the public-key encryption technology with a drive unit to check that the counterpart is an authorized (licensed) unit, and then gives the content key to the counterpart, thereby preventing data from being leaked to any illegal (unlicensed) unit. Thus, it is possible to prevent copyrighted data such as movie, music, etc. from being copied illegally (against the wish of the copyrighter of the data).
