MACsec 10G/25G

Overview

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

The core is configurable to have multiple Security Entities, SecYs, in a single IP to support multiple Connectivity Associations per port for traffic differentiation, and is prepared for easy interfacing with Comcores or third-party MAC, PCS and TSN Switch IPs.

The MACsec Engine implements 64-bit AXI-S input and output data interfaces. It offers flexibility on integration with IEEE 1588 PTP Timestamping Unit (TSU). It additionally includes a software tool for MACsec Key Agreement Protocol IEEE 802.1X integration.
