Title:
An Authentication Code over Galois Rings with Optimal Impersonation and Substitution Probabilities

Authors: Juan Carlos Ku-Cauich, Guillermo Morales-Luna, Horacio Tapia-Recillas

Abstract:

Two new systematic authentication code based on the Gray map over a Galois ring are introduced. The first introduced code attains optimal impersonation and substitution probabilities. The second code improves space sizes but it does not attain optimal probabilities. Besides it is conditioned to the existence of a special class of bent maps on Galois rings
