This paper first sequence passwords principle, meaning, the focus of its research and study status of the initial presentation, a detailed description of non-linear feedback shift register have a pseudo-random sequence of principle, Meanwhile de Bruijn of the sequence (commonly known as the M-series), the definition and determination methods described. The article described the latter part of the linear shift register integrated algorithm (also known as Berlekamp-Masse y algorithm), in principle briefed at the same time is given for the specific steps and C source code. Finally, the use of an implement of the proceres, The procere traverse n-de Bruijn sequence, the use of BM algorithm for the linear complexity, calculated with a linear complexity of n-de Bruijn sequence number, hence n-de Bruijn sequence of the total number. Through the proceres and operations on the results of the analysis shows that the BM algorithm code sequences important role.
