Abstract

An input data may be received. A portion of a cryptographic operation may be performed with the received input data at a first function component. During the performance of the cryptographic operation at the first function component, a pre-charge operation may be performed at a second function component. Furthermore, the second function component may be used to perform another portion of the cryptographic operation with a result of the portion of the cryptographic operation performed at the first function component.
