AES-256 Encryption IP Core

FIPS-197 AES-256 with XTS, GCM, CBC and CTR mode wrappers.

Overview

A standards-compliant AES-256 engine with mode wrappers for the two workloads that matter most: AES-256-XTS for sector encryption of data at rest (SED / OPAL SSD), and AES-256-GCM for authenticated encryption of data in flight (MACsec / IPsec / TLS offload). This core is on our roadmap — talk to us about early access and your target throughput.
