Implementation of the new LAN security standard 802.1ae (MACSec) requires the NIST standard AES cipher in the GCM mode for encryption and message authentication (AES-GCM). The GCM1 AES core is tuned for 802.1ae applications at the data rates of 1 Gbps and higher. The GCM2 family of cores is targeted towards high performance applications with high-end cores supporting data rates in excess of 100 Gbps and ability to parallelize to achieve even higher throughput. GCM3 is similar to GCM2, but supports AES key lengths up to 256 bits. For higher throughputs of 100 Gbps and above, use our GCM10 core family. Cores contain the base AES core AES1 and are available for immediate licensing. The design is fully synchronous and available in both source and netlist form.
