Abstract
In described embodiments, a unified Crypto Functional Unit (CFU) block architecture provides a capability for advanced communication processors to provide parallel and concurrent processing of multiple crypto operations/transactions within high-speed hardware to support different security standards (e.g. from IPsec, 3GPP). In particular, each CFU block of the unified CFU block architecture comprises a FIFO-based interface, switch, and wrapped cipher/hasher. The unified CFU block architecture allows for drop-in solutions for cipher blocks in ASIC designs with crypto function blocks.
