Reconfigurable circuits alternatively acting as Random Number Generators (RNGs) or Analog to Digital Converters (ADCs) represent a promising approach to true random bit generation since they can provide high quality random values almost for free whenever a system already embeds an ADC. In their usage, one needs to consider that entering the RNG-mode requires some minor interruption of operation, since the internal chaos-based random source gets initialised at the last ADC input. Hence, the first generated values maintain some dependence on a potentially known value and a few dead beats are needed by the chaotic system to reach a regime where this correlation vanishes. This delay has so far been quantified only empirically. Here, a formal bound is provided, with relation to the required performance level and the system noise floor.

Abstract

Reconfigurable circuits alternatively acting as Random Number Generators (RNGs) or Analog to Digital Converters (ADCs) represent a promising approach to true random bit generation since they can provide high quality random values almost for free whenever a system already embeds an ADC. In their usage, one needs to consider that entering the RNG-mode requires some minor interruption of operation, since the internal chaos-based random source gets initialised at the last ADC input. Hence, the first generated values maintain some dependence on a potentially known value and a few dead beats are needed by the chaotic system to reach a regime where this correlation vanishes. This delay has so far been quantified only empirically. Here, a formal bound is provided, with relation to the required performance level and the system noise floor.
