  • System and methods for encryption with authentication integrity
    Patent number: 8280056
    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, [TA1], in an initialization phase, to receive, during normal operation, two data entities of interest each including at least one data word of interest [TA2] and [TA3] respectively; to receive a first data entity including at least one word [TC1] comprising a randomized data entry, from the TX pseudorandom function generator, to generate a first XOR sum of the initialization data entity's word [TA1] and the at least one randomized data entity [TC1], in at least one iteration of an initialization phase; and, during normal operation, to generate and to output a second XOR sum [TA2?TC2=TB2] and a third XOR sum [TA3?TC3=TB3], wherein TB2 and TB3 are randomized data entities, wherein the words TA1, TA2 and TA3 are operative to initialize the data integrity sys
