Statistical analysis of the LFSR generators in the NIST STS test suite

Stępień R., Walczak J.

Computer Applications in Electrical Engineering

2013

Vol. 11

356--362

In this article the statistical tests results of the pseudo random sequences generated by the Linear Feedback Shift Registers (LFSR) generators were described. LFSR generators' structures were shown and used statistical tests were described. The generator output sequence was analyzed in the NIST Statistical Test Suite STS 2.1.1. Interpretation of data obtained from the NIST STS 2.1.1 and the analysis' results of the pseudo random test sequences were discussed.

Discrete models of the NLFSR generators

Walczak J., Stępień R.

Computer Applications in Electrical Engineering

2011

Vol. 9

181--189

In this article a class of pseudo random signal generators, build with static nonlinear feedback block, is described. The feedback block function is modeled as a linear combination of sums and products of the register’s taps. A discrete model of the generator is proposed as a nonlinear discrete circuit. The simulation results from Matlab-Simulink and Multisim are shown. Also an experimental results of the example generator on FPGA implementation is shown.
