    • An arithmetic unit and an arithmetic method that output no information necessary for decryption or encryption to the outside and can perform a self-protecting function when an illegal attack is made. A command monitoring part (44) monitors input command sequences. In a first sequence, a process key in a first stage is calculated from a hardware key (Khd) and is then written to a key storing part (47). In each of the following sequences, a process key in a next stage is calculated from a process key stored in the key storing part (47). When commands of predetermined contents are inputted in predetermined order, a content key is calculated and then written to the key storing part (47). Encrypted data is decrypted with the content key, and the result is outputted from data output means (63). When an illegal attack is made, initialization is performed by selecting fixed value data (Kf) as key data (Ksl) and selecting fixed value data (Df) as input data (Ein).

    • Disclosed is a key generator, which assures the security of a key by preventing a circuit designer and other persons from readily knowing the value of the key. Random number generator circuits (51, 52, 53 and so on) generate random numbers respectively in accordance with different clocks (CLK1, CLK2, CLK3, and so on). An arithmetic circuit (59) operates on the random numbers generated from the random number generator circuits (51, 52, 53 and so on) to generate an N-bit random number RA as the output from a random number generator (50). This N-bit random number is RA acquired via a key selector (43), and latched into a key register (45) in accordance with an acquisition enable signal EN from a timing monitoring counter (47), which is driven by a clock CLKA other than clocks CLK1, CLK2, CLK3, and so on, to obtain a hardware key, which is a unique secret key.

    • A data transfer apparatus for simplifying a module structure for controlling a connected data recording apparatus and improving the processing efficiency. A control code issued by a common application module having a main purpose of check-out/check-in is made a control code corresponding to a device connected by a conversion module and transmitted via a device driver. Moreover, for example, a control code issued by a local application module having a main purpose of controlling processing depending on a device connected shares the aforementioned device driver. For example, the local application module issues a control code in a state matched with a control code format converted by the conversion module. Alternatively, the local application module issues a local control code by indicating issuance of a local control code of a format different from the control code format converted by the conversion module.

    • A data transfer apparatus referred to as a primary-recording-medium apparatus implements proper system operations by acquisition of information on a secondary recording medium mounted on a secondary-recording-medium apparatus to serve as a destination of a transfer (or a check-out) of a content. If a medium adopting its own unique management technique as is the case with a mini disc is used as the secondary recording medium serving as a destination of a check-out, the primary-recording-medium apparatus acquires information on the secondary recording medium from the secondary-recording-medium apparatus, which is typically a data-recording apparatus. The information includes an indicator as to whether or not the secondary recording medium has been mounted on the data-recording apparatus, the name of the secondary recording medium, the name of each content stored in the secondary recording medium, the number of contents stored in the secondary recording medium and attributes of each content stored in the secondary recording medium.

    • Input data (plain text data or encrypted text data) are latched according to a clock CLK1 and, after initial transposition thereof, the data are outputted from a selector. The lower-order bits of the output data from the selector are processed through expanded transposition and then are calculated together with key data K1 in an XOR circuit, and the result data are latched according to a clock CLK2. The latched 48-bit data are divided into eight 6-bits data, each of which is then replaced with 4-bit data, and after combination thereof, the data are transposed. In the calculations of second and subsequent stages, the data obtained through replacement and combination in a replacement/combination circuit are latched according to the clock CLK1 and then are outputted from the selector. And after completion of the 16th-stage calculation, the data replaced in a replacement circuit are inversely transposed.
