Evaluation criteria for true (Physical) random number generators used in cryptographic applications

Abstract

Random number generators are essential components of many cryptographic systems. Inappropriate random number generators may weaken the security properties of the system considerably. This paper considers evaluation criteria for true (physical) random number generators. General objectives are formulated and possible criteria and measures are discussed which shall ensure these goals. Central parts of the mathematical-technical reference of the German evaluation guidance document AIS 31 ([19,2]) are cited and rationale is given. © Springer-Verlag 2003.
