    摘要： A liquid crystal display unit includes a control section. The control section reads LED electric current data stored in a storage section based on input information to control a backlight drive section, and controls an LCD panel based on the input information and a video signal. The backlight drive section provides a backlight with an electric current according to the LED electric current data. The LED electric current data outputted to the backlight drive section from the control section and image data outputted to the LCD panel from the control section are transmitted via a common signal line.

    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 bit sequence generation apparatus includes a glitch generating circuit that generates a glitch, a sampling circuit that samples the glitch waveform generated by the glitch generating circuit, and a glitch shape determination circuit that generates 1-bit data indicating either 1 or 0, based on the glitch waveform sampled by the sampling circuit, and generates a bit sequence composed of a plurality of generated 1-bit data. The bit sequence generation apparatus can provide a PUF circuit that is able to generate highly randomized secret information even in a device with a low degree of freedom of alignment and wiring and that does not violate the design rules.
