The 400G high-speed cryptography (HSC) engine implements an AES-GCM-256/128 engine that provides up to 400 Gb/s of bulk encryption capability on up to 40 channels that can be connected to the DCMAC. Each HSC engine supports both MACSec and IPSec at up to 400 Gb/s configurable as 1x400G, 2x200G, or 4x100G channels with up to 128 source addresses (SA) per 100G.
