Testing of generators of pseudo-random signals based on a Lorenz system, realized over a Galois finite field

FIPS 140-2 tests of new class of generators pseudorandom signals, built based on modified Lorenz system, realized over a Galois finite field were considered. Fixed point arithmetic were utilized in new class generators. The estimates of the correspondence of binary sequences formed on the basis of the Lorentz system to the requirements of the FIPS 140-2 test with the variation of the system parameters were obtained. The results of the work can be used in the construction of communication systems with broadband signals, modeling and cryptography.
