ABSTRACT:
A secure data processing unit has a data/program instruction memory for storing data/program instructions, an instruction line with a large number of function stages for processing the data/program instructions, and a control unit for controlling the function stages. A blank function generator in this case randomly produces blank functions in the data processing unit, thus making an eavesdropping attack by analysis of leakage information considerably more difficult or preventing it.
