System and methods for encryption with authentication integrity

Abstract

A data integrity system including a transmitter, having a TX pseudorandom function generator, a TX switching function having a transmitting option and a TX combiner operative to receive, from a Host, an initialization data entity including at least one word, [TA], in an initialization phase, to receive, during normal operation, two data entities of interest each including at least one data word of interest [TA] and [TA] respectively; to receive a first data entity including at least one word [TC] comprising a randomized data entry, from the TX pseudorandom function generator, to generate a first XOR sum of the initialization data entity's word [TA] and the at least one randomized data entity [TC], in at least one iteration of an initialization phase; and, during normal operation, to generate and to output a second XOR sum [TA⊕TC=TB] and a third XOR sum [TA⊕TC=TB], wherein TBand TBare randomized data entities, wherein the words TA, TAand TAare operative to initialize the data integrity system including enabling the data integrity system to encrypt the TAword and to generate an identifying hash value output using the TAword.
