Abstract

A method is performed with a group of chiplets. The method includes: (1) parsing a message into at least a group of ordered message blocks associated with a group of index values, which are indicative of positions of individual message blocks relative to one another; (2) generating two or more substitution values based at least in part on execution of two or more pseudo-random number generators (PNRG's) using seeds associated with the bits of blocks of the group of message blocks; (3) generating two or more sequencing values based at least in part on execution of two or more PNRG's using seeds associated with index values of the group of index values; (4) generating a group of ciphertext blocks at least in part with XOR operations using at least the substitution values and the sequencing values; (5) concatenating the group of ciphertext blocks; and (6) transmitting.
