Abstract
A scalable and efficient cryptographic architecture is provided for processing data using deeply-pipelined algorithms and circuitries. The architecture can be implemented as circuitry in a fixed logic device, or can be configured into a programmable integrated circuit device. The same top-level design may be used for different choices of data channels, processing depth, parallelism level, and/or system throughput. An encryption pipeline processing block performs rounds of processing upon a block of said data using an encryption process and receives a respective round encryption key for each round of processing. An encryption key pipeline block provides the respective round encryption key for each round of processing by selecting, for each round of processing, the respective round encryption key from at least a first round encryption key corresponding to a first channel and a second round encryption key corresponding to a second channel.
