A different kind of True Random Number Generator - Stoachastic Assembly of Ag/Au Single Particle Lines — •Daniel Schletz1, Martin Mayer1,2, Anja Maria Steiner1,2, and Andreas Fery1,2,31Leibniz-Institut für Polymerforschung Dresden e.V., Germany — 2Cluster of Excellence Center for Advancing Electronics Dresden, Germany — 3Department of Physical Chemistry of Polymeric Materials TU Dresden, Germany

Standard hardware random number generators often use quantum mechanical phenomena or thermal noise to produce bit streams of random, but often biased, origin. In contrast, colloidal self-assembly of billions of particles on 1 cm2 can assure bias-free, heterogeneous particle sequences to be employed as bits in a hardware random number generator.

Utilizing template-assisted colloidal self-assembly of two different particle types (Au spheres and Ag spheres), heterogeneous single particle lines are assembled and subsequently analyzed via electron microscopy. Statistical evaluation shows that Ag and Au do not assemble in any way preferential to any particle type, generating random distributions only dependent on employed Ag/Au particle share.
