CLP-16: Ultra-High Throughput AES-GCM Core - 10 Gbps

The Galois/Counter Mode (GCM) algorithm has been proposed to provide for high-speed (20/40 Gbps and beyond) encryption and authentication. GCM uses a block cipher in counter mode together with Galois Field based authentication to get past the performance limitations of using block ciphers for authentication (e.g. AES-CBC-MAC). Elliptic's AES-GCM core uses a binary Galois Field Multiplier (GFM) for authentication, together with a high-performance AES-CTR mode cipher to provide high-speed encryption and authentication. It provides both AES-GCM and GMAC-AES functionality.

Key Features:

• Throughput up to 40 Gbps
• Implements AES-GCM as specified in draft IEEE standard 802.1AE
• Multiple message authentication modes:
  • Stand-alone
  • Authentication without encryption
  • Incremental authentication of header data
• Test bench and synthesis scripts provided

Applications:

• WAN Security - OC-48, OC-192 and OC-768
• EPON - Passive Optical Networking
• Ethernet link security such as 802.1AE
• IPsec
• SAN/NAS
