ABSTRACT:
Circuitry for encrypting at least a part of an input data flow and generating a tag based on the input data flow with the same ciphering algorithm and the same key including a first ciphering branch arranged to encrypt the at least part of the input data; a second ciphering branch arranged to generate the tag; and a single key schedule unit arranged to receive the key, to generate at least one sub-key based on the key and to provide the at least one sub-key to the first and second ciphering branches.
