Posedge Inc 
Short Desc. : posedge-L2SEC --IEEE802.1AE (MACsec) Processing Engine/L2 Security Engine
Overview :
PE-L2SEC implements the complete MACsec data plane functionality. It performs functions such as AES-GCM, Packet 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. The size of the core is around 400K gates for a 10Gbps configuration in 65 nm.

Posedge-L2sec implements MACsec data plane specification (Full 802.1AE standard compliant). MACsec is defined as per 802.1AE and 802.1AF standards. It is primarily used to safeguard communication between trusted components of the network infrastructure and to provide controlled access to the network.

802.1AE defines MAC layer traffic protection. It offers hop-by-hop link layer security based on symmetric key AES-GCM encryption and authentication. MACsec allows multiple security associations per physical port and protects the entire Ethernet frame including MAC DA (Destination Address) and MAC SA (Source Address) from being spoofed. The key negotiation is as per the 802.1AF which is an enhancement of 802.1x to provide symmetric key for MAC layer protection. 802.1AF is implemented in the software.
