Posedge-L2SEC – High-Performance IEEE 802.1AE (MACSec) Processing Engine

MACSec provides data confidentiality, data integrity, and data origin authentication at the link layer (Layer-2 of the OSI model) using AES-GCM (Galois Counter Mode) self-authenticating cipher.

Posedge-L2SEC implements the complete MACSec data plane functionality. It performs functions such as AES-GCM, Classification & Filtering, SecTAG processing, Anti-Replay check, ICV verification, and MIB Statistics. The engine can process the MAC frames up to 10Gbps full-duplex throughput for all packet sizes. It is highly configurable and easy to  integrate.
