MACsec Engine
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.

What is TSN?
Morten Kofoed Esbjørn - Feb 14, 2023. TSN, or Time-Sensitive Networking, is a technology based on the IEEE 802.1Q standard. It has evolved from the Ethernet technology currently used to carry all types of traffic, for which ethernet was not originally intended, such as multiple data flows with different timing requirements, commonly found in Audio Video Bridging (AVB), automotive and industrial automation applications. TSN sits in Layer 2 of the OSI Model (figure 1).Figure 1: Illustration of...
