If an efficient representation of a field element in one basis exists, then field arithmetic in the hardware and/or software implementations becomes easy. Otherwise, a basis conversion to an efficient one is searched for easier arithmetic. However, this conversion often brings a storage problem for transition matrices associated with these bases. In this paper, we study this problem for conversion between normal and polynomial bases in the extension field Fqp over Fq where q p n . We construct transition matrices that are of a special form. This provides free storage basis conversion algorithms between normal and polynomial bases, which is crucial from the implementation point of view.eninfo:eu-repo/semantics/openAccessWelding oscillatorAutomationControlSmart weldingStepper motorArticle41196109Q2WOS:000392340700010Q310.3906/mat-1503-84
