  • Publication number: 20140122903
    Abstract: A semiconductor device includes a CPU, an EEPROM, and a ROM. The ROM includes an encryption area and a non-encryption area and the encrypted firmware is stored in the encryption area. The semiconductor device includes a decrypter which holds the encryption key, decrypts the encrypted firmware, and supplies the decrypted firmware to the CPU. The EEPROM includes a system area to which an access from the CPU is forbidden in a user mode. The encryption key is divided into split keys of plural bit strings, and stored in the distributed address areas in the system area. An encryption key reading program which is not encrypted is stored in the non-encryption area of the ROM. Executing the encryption key reading program, the CPU reads and reconfigures plural split keys stored in the EEPROM in a distributed manner to restore the encryption key and supplies the restored encryption key to the decrypter.

  • Patent number: 8595275
    Abstract: The present invention is directed to improve leak analysis resistance by improving randomness of a pseudorandom number. A pseudorandom number generator as a representative embodiment of the invention includes a shift resistor obtained by coupling a plurality of flip flop circuits and can generate a pseudorandom number by shifting signals by the shift register synchronously with a clock signal. A shift amount changing circuit capable of changing a shift amount in the shift register in accordance with a control signal supplied from the outside of the pseudorandom number generator is provided. By changing the shift amount in the shift register in accordance with a control signal supplied from the outside of the pseudorandom number generator by the shift amount changing circuit, it becomes difficult to make outputs of the pseudorandom number generator the same. By using such a pseudorandom number generator, leak analysis resistance can be improved.

  • Publication number: 20130247543
    Abstract: An exhaust gas control apparatus includes a control device controlling a urea addition valve for adding urea from an upstream side of a NOx reduction catalyst. The control device obtains an ammonia adsorption amount distribution through the NOx reduction catalyst. When an ammonia adsorption amount in a predetermined part on a downstream side equals or exceeds a predetermined threshold, the control device controls the urea addition valve to stop the urea supply or reduce the amount thereof. The urea addition valve is controlled based on an adsorption amount distribution obtained from a model on which the catalyst is divided into cells such that an ammonia adsorption amount in a first cell positioned furthest upstream equals or exceeds a predetermined threshold close to a saturation adsorption amount and an ammonia adsorption amount in a second cell positioned downstream of the first cell reaches a predetermined target value smaller than the threshold.

  • Patent number: 8266450
    Abstract: It is possible to achieve the protection of software with reduced overhead. For example, a memory for storing an encrypted code prepared in advance and a decryptor module for decrypting the code are provided. The decryptor module includes, for example, a three-stage pipeline and a selector for selecting one output from the outputs of each stage of the pipeline. When a branch instruction is issued and subsequent inputs of the pipeline are in the order of CD?1, CD?2, . . . , the decryptor module outputs a first decrypted code by performing a one-stage pipeline process to CD?1. Next, the decryptor module outputs a second decrypted code by performing a two-stage pipeline process to CD?2, and the decryptor module outputs a third decrypted code by performing a three-stage pipeline process to CD?3 (and subsequent codes). Therefore, in particular, the overhead to CD?1 can be reduced.
