The paper establishes a connection between the theory of permutation polynomials and the question of whether a de Bruijn sequence over a general finite field of a given linear complexity exists. The connection is used both to construct span 1 de Bruijn sequences (permutations) of a range of linear c

We give a complete resolution to a conjecture regarding the characterisation of linear complexities of span 1 de Bruijn sequences over nonprime finite fields. This contrasts with results for prime fields, where the characterisation is equivalent to an open question concerning permutation polynomials
It has been conjectured that over any non-prime finite field F p m and for any positive integer n, there exists a span n de Bruijn sequence over F p m which has the minimum possible linear complexity p nm&1 +n. We give a proof by construction that this conjecture is true.
