Combo P1619 / 802.1ae (MACSec) GCM-AES/LRW-AES Cores
LAN security standard IEEE 802.1ae (MACSec) uses AES cipher in the GCM mode, while the disk/tape encryption standard IEEE P1619 uses the LRW mode. Since AES-GCM and AES-LRW share some of their basic components, a combo GCM-AES/LRW-AES core is not much larger than a dedicated core for either of the modes.
The GLM1 core is tuned for mid-performance P1619 and 802.1ae applications at the data rates of 3-5 Gbps and higher. GLM2 is designed for higher throughput up to 10 Gbps. Both cores use identical external interface, contain the base AES core AES1 and are available for immediate licensing.
GLM3 core is similar to GLM2, but its interface supports variable message length in the GCM mode.
The design is fully synchronous and available in both source and netlist form.
