Some constructions of systematic authentication codes using Galois rings (Q2383975)

The authors look at authentication codes over finite fields by employing Galois rings. In the process they provide corrections to the estimates given in ``\(A\)-codes from rational functions over Galois rings'' [Des. Codes Cryptography 39, No. 2, 207--214 (2006; Zbl 1118.14030)]. Moreover, they provide generalizations of results in the literature.
