摘要： A DMA controller is connected by a bus to a plurality of master devices and a plurality of slave devices, and performs a data transfer between slave devices which are specified as a source and a destination of the data transfer by a transfer condition received from any of the plurality of master devices. Each of the plurality of master devices and the plurality of slave devices has a rank used for judging data transfer permissibility. The DMA controller enables the data transfer if the data transfer is judged to be permitted as a result of a comparison between a rank of the master device and a rank of any of the specified slave devices, and disables the data transfer if the data transfer is judged to be prohibited.

摘要： A check computation circuit executes a computation corresponding to a computation for generating confidential CRC data, with respect to confidential data read from a non-volatile device. A comparison circuit compares the result of the computation in the check computation circuit with confidential CRC data read from the non-volatile device. When the result of the comparison indicates a mismatch, i.e., an error is detected, an encryption circuit encrypts the confidential data and the confidential CRC data using a secret key registered in a secret key register, and outputs the encrypted confidential data and confidential CRC data to the outside of a semiconductor integrated circuit.

摘要： The present invention relates to a confidential information processing device, a confidential information processing apparatus, and a confidential information processing method, and particularly to a confidential information processing device which performs multiple cryptographic computation for different target data included in a data stream. With this configuration, the context control unit outputs the stream on which the cryptographic computation is performed to an external device or other stream analysis unit. Thus, by setting the number of cryptographic computation on a correspondence table, the number of computation can be set to any number. Thus, the confidential information processing device according to the present invention can perform any number of cryptographic computations on one stream. Furthermore, without outputting the stream whenever a cryptographic computation is completed, multiple cryptographic computations can be performed with one stream input. In addition, by setting the number of cryptographic computation on the correspondence table, the number of computation can be easily changed.
