US 12,700,989 B2 · Cryptographic processor for ciphertext applications

Abstract

Cryptographic processor chips, systems and associated methods are disclosed. In one embodiment, a cryptographic processor is disclosed. The cryptographic processor includes a first cryptographic processing module to perform a first logic operation. The first cryptographic processing module includes first input circuitry to receive ciphertext input symbols. A first pipeline stage performs a first operation on the ciphertext input symbols and generates a first stage output. On-chip memory temporarily stores the first stage output and feeds the first stage output to a second pipeline stage in a pipelined manner. The second pipeline stage is configured to perform a second operation on the first stage output in a pipelined manner with respect to the first pipeline stage.
