Abstract

In a method for generating a cipher-based message authentication code, a state array (25) comprised of rows (31-34) of bytes (S′0-S′15) and columns (41-44) of bytes (S′0-S′15) based on a message to be transmitted is generated. The cipher-based message authentication code is generated by retaining the bytes (29, 30) of at least one row (32, 34) of the state array (25).
