Abstract
A combination firmware and hardware cryptographic core architecture is provided for encrypting, decrypting and authenticating data. The core provides flexibility to change and add new cryptographic protocols, while providing increased performance by loading new firmware into a microcontroller that programs behavior of various components in the core. The core combines a microcontroller programmable by firmware, and flexible aligner, insertion and removal controllers programmed by the microcontroller that process, manage and manipulate an incoming data stream as it moves through the core. The firmware may be reprogrammed upon an enhancement or change to a protocol while still realizing performance benefits of the hardware. Reprogramming the microcontroller allows it to change the way the aligner, insertion and removal controllers manipulate the data stream as it enters various components. Such systems provide redesign time savings compared to hardware cryptographic core architectures, and improved speed and throughput compared to software cryptographic core architectures.
