Analysis of the certification of quantum random number generators by Bell's theorem — •Rainer Plaga — Bundesamt für Sicherheit in der Informationstechnik (BSI), 53175 Bonn, Godesberger Allee 185-189

S.Pironio et al. describe a qualitatively novel method to certify quantum random number generators ("Random numbers certified by Bell's theorem" (Nature 464, 1021 (2010)). A qualitative simplification and/or improvement of the IT-security certification of a component which is as important for IT-security as random number generators is a potentially important new practical application of quantum information technology.

The new method is systematically compared to the standard "model based" approach recommended by the BSI for the certification of physical random number generators when it would be applied to Pironio et al.'s device. The possible advantages of and remaining problems with Pironio et al.'s methodology are discussed.
