Title:
On the security of MQ_DRBG

Authors: V. O. Drelikhov, G. B. Marshalko, A. V. Pokrovskiy

Abstract:

MQ_DRBG is a pseudorandom number bit generator proposed for international standardization by the French national organization for Standardization (AFNOR). It makes use of a specific instantiation of a one-way function S:\ftwo^n\rightarrow \ftwo^{n+r} based on quadratic multivariate polynomials. We describe two methods for constructing function S, satisfying requirements of the proposed draft, but having less security level.
