EFFICIENT HARDWARE IMPLEMENTATION OF TWEAKABLE BLOCK CIPHER

摘要

A combination of an infrequently-called tiny multiplication unit and a "differential" unit that quickly computes T (n+1) basing on known T n. The schedule (how often the multiplication unit is called) can be considered as a parameter of the algorithm. The proposed architecture of the "differential" unit is efficient both in terms of speed (delay) and area (gate count).
