Xiphera's extreme speed MACSEC IP core implements the MACsec protocol as standardized in IEEE Std 802.1AE-2018. The MACsec protocol defines a security infrastrucure for Layer 2 (as per the OSI model) traffic by assuring that a received frame has been sent by a transmitting station that claimed to send it. Furthermore, the traffic between stations is both encrypted to provide data confidentiality and authenticated to provide data integrity.
