Abstract :
A post-processing function is used to reduce or eliminate statistical weaknesses of physical random number generators. The output bias of a n-bit input m-bit output function is examined, when the input bits are biased. For this purpose, the definition of (n, m, t)-corrector is introduced; many characterizations and properties of a corrector are presented. It appears as a generalization of the notion of resilience for a vectorial function. Several constructions of correctors from old correctors are also proposed.
