P1619/802.1ae (MACSec) GCM/XEX/XTS-AES Core

General Description LAN security standard IEEE 802.1ae (MACSec) uses AES cipher in the GCM mode, while the disk/tape encryption standard IEEE P1619 uses the XEX/XTS mode. Since GCM and XEX/XTS share some of their basic components, a combo GCM/XEX/XTS core is not much larger than a dedicated core for either of the modes.

The GXM3 core is tuned for mid-performance P1619 and 802.1ae applications at the data rates of 2-3 Gbps and higher. The core contains the base AES core AES1 and is available for immediate licensing.

The design is fully synchronous and available in both source and netlist form.
