Binary random-number generator for generating sequence of random bits in e.g. cryptographic applications, has downstream digital signal processing unit for producing sequence of random bits

摘要

The generator has a sum-and-difference amplifier (5) whose inputs are symmetrically connected to two electrodes of a semiconductor element (1) i.e. breakdown diode, for adjusting signal difference of an analog noise signal produced at the electrodes to an input signal range of an analogue-digital converter (7). The converter is provided for digitizing the intensified signal difference. A downstream digital signal processing unit (8) is provided for digital continuous processing of scanning values of the digitized signal difference and for producing sequence of random bits.
