MACsec Engine


Comcores MACsec IP provides Ethernet Layer 2 Security for data confidentiality and data integrity as standardized in IEEE 802.1AE. It protects components in Ethernet network especially high-speed Ethernet used in cloud, data center, 5G, industrial and automotive. The MACsec IP is a fully compliant solution with a fixed latency that provides line-rate encryption and supports VLAN-in-clear.

The core is configurable and is prepared for easy interfacing with Comcores MAC and PCS solutions. It implements 64-bit AXI-S input and output data interfaces. It offers flexibility on integration with IEEE1588 timestamping and Express and Preemptable traffic. It additionally includes a software tool for MACsec Key Agreement Protocol IEEE 802.1X integration.
