基于串聯(lián)寄存器和純輪換寄存器構(gòu)造de Bruijn序列的研究
[Abstract]:Sequences are widely used in cryptography, communication and other security fields. With the development of correlation attacks and algebraic attacks, nonlinear feedback shift register (NFSR) instead of linear feedback shift register (LFSR) becomes the focus of sequential cryptography design. As a very special and important NFSR sequence, de Bruijn sequence has always been a hot topic in the field of sequence research. In this paper, two methods of constructing de Bruijn sequences are studied. The first is to construct de Brui-jn sequences based on series registers. Firstly, the mutual transformation of LFSR between series and parallel is given, and then according to this relation, A special structure of NFSR string LFSR is given. In this paper, the loop structure of the series structure is studied, the method of finding the output sequence with small period is given, and the judgment and selection of conjugate state between the sequence and other output sequences are analyzed, and the de Bruijn sequence is obtained by multiple cycles. The second is to construct deBruijn sequences based on pure rotation registers. Firstly, the cycle structure of pure rotation shift registers is studied, the relationship between the number of pure rotation registers and the number of cosets is given, and then the de Bruijn sequences are constructed by inserting method. The two methods of constructing de Bruijn sequences in this paper enrich the study of de Bruijn sequences and have better theoretical value and application value.
