Comcores MACsec IP provides Ethernet Layer 2 Security for data confidentiality and data integrity as standardized in IEEE 802.1AE. The MACsec IP protects components in Ethernet networks especially high-speed Ethernet used in 5G networks, industrial, automotive and cloud industries. The MACsec IP is a fully compliant solution that provides line-rate encryption, it is configurable to support multiple Connectivity Associations (SecYs) for traffic differentiation, and supports VLAN-in-clear.

The MACsec solution additionally includes a software tool for MACsec Key Agreement Protocol IEEE 802.1X integration.

The MACsec IP can be delivered as a Packaged IP Solution integrated with Comcores MAC, PCS, IEEE 1588 PTP Timestamping Unit (TSU), and TSN Switch IPs. The Packaged IP Solution will reduce your integration effort and accelerate your time-to-market.
