BittWare Partner IP

MACsec IP Core

IEEE 802.1AE IP Core

The Xiphera MACsec family provides high-speed IP cores implementing the MACsec (Media Access Control security) 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. The traffic between stations is also encrypted to provide data confidentiality and authenticated to provide data integrity.

Typical MACsec applications require high data bandwidths such as 10G, 25G, or 40G and often benefit greatly from FPGA-based acceleration. The Xiphera MACsec IP runs on BittWare’s IA-840F and IA-420F Agilex FPGA-based PCIe cards.

Functionality

Empty heading

The Xiphera MACsec IP uses Advanced Encryption Standard with a 128 or 256-bit key in Galois Counter Mode (AES-GCM) to protect data confidentiality, data integrity and data origin authentication. XIP1213H is best suited for data traffic on 25 Gbps links.

Use Cases

Empty heading

The original use case for MACsec is protecting communications in wired local area networks. MACsec can also be used for the following:

  • To protect critical control messages in communications networks
  • To protect sensitive measurement data in industrial automation applications
  • To secure point-to-point video links
