Abstract

There is disclosed an apparatus, and corresponding method, operable to perform an FI function of a Kasumi algorithm, including a reconfigurable processing stage, wherein in a first configuration the processing stage implements a first stage of the FI function and in a second configuration the processing stage implements a second stage of the FI function.
