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 very low-speed Ethernet used in automotive, industrial, and consumer applications. The MACsec IP is a fully compliant solution that provides line-rate encryption and is optimized for the smallest area size.

The MACsec 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. It implements 8-bit AXI-S input and output data interfaces and can be delivered with GMII interfaces for placement below the MAC. It additionally includes a software tool for MACsec Key Agreement Protocol IEEE 802.1X integration including AUTOSAR and FreeRTOS.
