    • A data processing apparatus is provided, which detects falsification of software to data and rewriting of the data. The data processing apparatus according to an embodiment of the present invention comprises a security unit which has an encryption circuit for decrypting an encrypted signal including secrecy data. The security unit includes a compression circuit which compresses an access signal used in accessing the security unit and outputs the compression result, and a comparison circuit which compares the compression result outputted from the compression circuit with a previously-calculated expectation value of the compression result of the access signal.

    • After a selection key bundle is determined by a selection key bundle determining process, the following first authentication key authenticating process is executed. An authentication processing part selects a selection encryption key from selection key bundle following a predetermined association based on a received random-number data. On the other hand, another authentication processing part selects an encryption key from the selection key bundle as a selection encryption key, following the association based on the received random-number data, encrypts the random-number data using the selection encryption key so as to acquire encrypted random-number data and transmits to the former authentication processing part. The former authentication processing part decrypts the encrypted random-number data using the selection encryption key so as to acquire decrypted random-number data and then determines whether that authentication is acceptable based on a comparison between the transmission time original random-number data and decrypted random-number data.
    • 在通过选择密钥束确定处理确定了选择密钥束之后,执行以下第一认证密钥认证处理。 认证处理部基于接收到的随机数数据,在预定关联之后从选择密钥束中选择选择加密密钥。 另一方面,另一认证处理部从选择密钥包中选择加密密钥作为选择加密密钥,根据接收的随机数数据进行关联,然后使用选择加密密钥加密随机数数据,从而 获取加密的随机数数据并将其发送到前一认证处理部分。 前一认证处理部分使用选择加密密钥对加密的随机数数据进行解密,以便获取解密的随机数数据,然后基于传输时间原始随机数数据和解密随机数之间的比较来确定该认证是否可接受 数字数据。
