High-Performance IEEE 802.1AE (MACSec) Processing Engine by Posedge Inc

SoC IP Provider

Product Description

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.

Features:

• Complete inline processing without software intervention in the datapath
• Up to 10Gbps full duplex throughput & low Latency with short packets
• Fully compliant with IEEE 802.1AE standard
• Configurable number of Secure Associations per port with double buffering of SA
• AES-GCM as defined by the IEEE standard support for Crypto and Authentication
• Decryption and ICV verification on Ingress
• Anti-replay verification on Ingress
• Encryption and Authentication with ICV generation and insertion on Egress
• MACSec header insertion and removal
• Supports hardware based packet classification
• MIB counter update as per the MACSec Standard
