METHODS AND APPARATUS FOR PROVIDING A MESSAGE AUTHENTICATION CODE USING A PIPELINE

摘要

Methods and apparatus provide for: dividing a quantity of data values into a plurality of blocks; dividing the plurality of blocks into respective sub-sets of blocks; computing an intermediate message authentication code block for each sub-set of blocks by performing a first cipher block chaining algorithm on the blocks of each sub-set of blocks; and computing a message authentication code block for the plurality of blocks by performing a second cipher block chaining algorithm on the intermediate message authentication code blocks.
