A first chiplet parses at least a message into ordered message blocks that are associated with index values. The first chiplet generates a substitution value by executing a pseudo-random number generator using a seed value that is computed with at least (i) a first random or pseudo-random number and at least (ii) a first message block. The first chiplet generates a sequencing value by executing a pseudo-random number generator using a seed value that is computed with at least (i) a second random or pseudo-random number and at least (ii) an index value for the first message block. The first chiplet generates a first ciphertext block with at least the substitution value and the sequencing value and further generates a second ciphertext block at least partly with the first ciphertext block. The blocks are concatenated and transmitted to a second chiplet.

PRNG-based chiplet-to-chiplet secure communication using chaining of message blocks

A system and method for a switching network is disclosed. A plurality of first switching assemblies, second switching assemblies and intermediate switching assemblies with each of the first switching assemblies, second switching assemblies and intermediate switching assemblies having at least two input ports and output ports is provided. Selective one of the two input ports is configured to receive a data to be processed and delivered at a designated one of the output ports. Received data passes through one or more selective first switching assemblies, one or more intermediate switching assemblies and one or more selective second switching assemblies, before the received data is delivered to the designated port. A plurality of additional data is received in one or more of the input ports to be delivered to one or more designated output ports is processed before the received data is delivered to the designated one of the output ports.

System and method for a pipelined multi-layer switching network

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.
