Giesbrecht's algorithm, the HFE cryptosystem and Ore's -polynomials
Robert S. Coulter, George Havas, Marie Henderson
We report on a recent implementation of Giesbrecht's algorithm for factoring polynomials in a skew-polynomial ring. We also discuss the equivalence between factoring polynomials in…

On the splitting case of a semi-biplane construction
Robert S. Coulter, Marie Henderson
We consider the case where a particular incidence structure splits into two substructures. The incidence structure in question was used previously by the authors to construct semi-…
