Abstract

An authentication-encryption unit provides at least one encryption element, where each encryption element encrypts a plain-data block and accordingly generates a cipher-data block. A common checksum is calculated over each cipher-data block. It is possible to select via a selection unit in each encryption element which data bits in each cipher-data block are to be used to calculate the common checksum.
