A method comprising the steps of creating a random permutation of data from a data input by executing at least one of a Pseudo-Random Permutation (PRP) and a Pseudo-Random Function (PRF), creating a first data block by combining the random permutation of data with a received second data block and executing an epsilon-differentially uniform function on the result of the combination, XORing the result of the epsilon-DU function evaluation with a secret key, and reducing the first data block to a first message authentication code.
