Slice-aggregated cryptographic system and method

Abstract:

A system comprises one or more slice-aggregated cryptographic slices each configured to perform a plurality of operations on an incoming data transfer at a first processing rate by aggregating one or more individual cryptographic slices each configured to perform the plurality of operations on a portion of the incoming data transfer at a second processing rate. Each of the individual cryptographic slices comprises in a serial connection an ingress block configured to take the portion of the incoming data transfer at the second processing rate, a cryptographic engine configured to perform the operations on the portion of the incoming data transfer, an egress block configured to process a signature of the portion and output the portion of the incoming data transfer once the operations have completed. The first processing rate of each slice-aggregated cryptographic slices equals aggregated second processing rates of the individual cryptographic slices in the slice-aggregated cryptographic slice.
