We derive B\'ezout identities for the minimal polynomials of a finite sequence and use them
to prove a theorem of Wang and Massey on binary sequences with a perfect linear
complexity profile. We give a new proof of Rueppel's conjecture and simplify Dai's original
proof. We obtain short proofs of results of Niederreiter relating the linear complexity of a
sequence s and K (s), which was defined using continued fractions. We give an upper
bound for the sum of the linear complexities of any sequence. This bound is tight for …
We derive B\'ezout identities for the minimal polynomials of a finite sequence and use them to prove a theorem of Wang and Massey on binary sequences with a perfect linear complexity profile. We give a new proof of Rueppel's conjecture and simplify Dai's original proof. We obtain short proofs of results of Niederreiter relating the linear complexity of a sequence s and K(s), which was defined using continued fractions. We give an upper bound for the sum of the linear complexities of any sequence. This bound is tight for sequences with a perfect linear complexity profile and we apply it to characterise these sequences in two new ways.
