Abstract

A new proposal to generate pseudorandom numbers with Gaussian distribution is presented. The generator is a generalization to the extended field G F ( 2 n ) of the one using cyclic rotations of linear feedback shift registers (LFSRs) originally defined in G F ( 2 ) . The rotations applied to LFSRs in the binary case are no longer needed in the extended field due to the implicit rotations found in the binary equivalent model of LFSRs in G F ( 2 n ) . The new proposal is aligned with the current trend in cryptography of using extended fields as a way to speed up the bitrate of the pseudorandom generators. This proposal allows the use of LFSRs in cryptography to be taken further, from the generation of the classical uniformly distributed sequences to other areas, such as quantum key distribution schemes, in which sequences with Gaussian distribution are needed. The paper contains the statistical analysis of the numbers produced and a comparison with other Gaussian generators.
