Media Access Control Security (MACsec) has been specified by the IEEE as a layer 2 security scheme. It is compatible with the revised IEEE 801.1X-2010 specification for port based Network Access Control and provides additional security for all Ethernet traffic types.
The MACSEC core is a high performance pipelined implementation of IEEE standard 802.1ae. The core is built on Algotronix' pipelined 40G implementation of the AES-GCM encryption algorithm which itself builds on our G3 AES core. Other versions of our MACSEC core support operation at 1Gbit/sec and 10Gbit/sec.
