Abstract

Disclosed is an apparatus and method for encrypting plaintext data. The method includes: receiving at least one plaintext data input; applying a Nonce through a function to the at least one plaintext data input to create Nonced plaintext data outputs and/or to intermediate values of a portion of an encryption function applied to the at least one plaintext data input to create intermediate Nonced data outputs; and applying the encryption function to at least one of the Nonced plaintext data outputs and/or the intermediate Nonced data outputs to create encrypted output data. The encrypted output data is then transmitted to memory.
