    摘要: In initial generation (for example, shipping from the factory), a security device generates an identifier w specific to the security device, with the PUF technology, generates key information k (k=HF(k)) from the identifier w, generates encrypted confidential information x by encrypting (x=Enc(mk, k)) confidential information mk with the key information k, and stores the encrypted confidential information x and an authentication code h (h=HF′(k)) of the key information k, in a nonvolatile memory. In operation, the security device generates the identifier w with the PUF technology, generates the key information k from the identifier w, and decrypts the encrypted confidential information x with the key information k. At a timing where the identifier w is generated in the operation, the security device checks whether the current operating environment has largely changed from the initial generation (S311). If a change in operating environment is detected (S311→S312), the security device conducts a reset-up process (S312 to S315) of an authentication code h which is confidential information, and the encrypted confidential information x.

    摘要: A charge controller includes a charge control circuit that, when detecting that a charging power supply is connected, controls the charging transistor to apply the charge current; a first and second control switch element connected in series between one terminal of a secondary battery and an external terminal; and a protection circuit that, when the secondary battery is over-discharged, turns off the first control switch element to stop discharge current and when deeply discharged, turns off the second control switch element. The protection circuit sends a charge inhibit signal to the charge control circuit when the secondary battery is deeply discharged, and while receiving the charge inhibit signal, the charge control circuit keeps the charging transistor off to prevent the charge current from flowing even if detecting that the charging power supply is connected.

    摘要: A region determination circuit (60) determines whether or not each of the pixels in an image is within a region subject to correction, in which pixels having at most a predetermined brightness level appear with a frequency equal to or less than a predetermined value. An offset level generation circuit (10) generates an offset level (Offset) on the basis of the brightness of the pixels determined to be within the region subject to correction. An offset subtraction circuit (1) subtracts the offset level (Offset) from the image signal (Yi) to generate an offset image signal (Yofst). A gain generation circuit (20) generates a gain for the offset image signal (Yofst). A gain multiplication circuit (2) multiplies the offset image signal (Yofst) by the gain to generate a corrected image signal (Ya).

    摘要: A bit generation apparatus includes a glitch generation circuit that generates glitch signals which include a plurality of pulses, and T-FF bit generation circuits which input the glitch signals, and based on either rising edges or falling edges of the plurality of pulses included in the glitch signals, generate a bit value of either 0 or 1. Each of the T-FF bit generation circuits generates a respective bit value based on either the parity of the number of rising edges or the parity of the number of falling edges of the plurality of pulses. As a result of employment of the T-FF bit generation circuits, circuits that are conventionally required but not essential for the glitch become unnecessary. This serves to prevent expansion in circuit scale and increase in processing time of bit generation for the bit generation circuit.
