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.

โฆ Synopsis
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.
