Title:
BIT SEQUENCE GENERATION DEVICE AND BIT SEQUENCE GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/086688
Kind Code:
A1
Abstract:
A bit sequence generation device (200) is provided with a glitch generation circuit (205) for generating glitches; a sampling circuit (220) for sampling glitch waveforms generated by the glitch generation circuit (205); and a glitch form assessment circuit (211) for generating 1-bit data representing either 1 or 0 on the basis of the glitch waveform that has been sampled by the sampling circuit (220), and generating a bit sequence comprising the generated plurality of 1-bit data. By way of the bit sequence generation device (200), it is possible to provide a PUF circuit that is capable of generating highly randomized secret information and that does not violate design rules, even for a device with a low degree of freedom for placing and routing thereof.
