Abstract

We describe a new application of algebraic coding theory to universalhashing and authentication without secrecy. This permits to make use of thehitherto sharpest weapon of coding theory, the construction of codes fromalgebraic curves. We show in particular how codes derived from Artin-Schreiercurves, Hermitian curves and Suzuki curves yield classes of universal hashfunctions which are substantially better than those known before.
