Apparatus for clocked power logic against power analysis attack

摘要

A logic apparatus secure against a power analysis attack is disclosed. The logic apparatus may include a clocked power logic to recover and reuse at least a part of charges supplied during a single clock operation; a first device block connected to the clocked power logic to remove a parasitic capacitance difference in the clocked power logic, and a second device block to readjust remaining charges in each node of the clocked power logic after a single clock operation.
