Overview
Flexible and Silicon proven Ethernet Layer 2 Security solution
The 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 automotive, industrial, cloud, data center, and wireless infrastructure. The MACsec IP is a fully compliant solution that provides line-rate encryption and supports VLAN-in-Clear.
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 or 64-bit AXI-S input and output data interfaces, and can be delivered with (X)GMII interfaces for placement below the MAC. 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.

With 5G being deployed for time-sensitive applications, security is becoming an important consideration. At the same time, Open Radio Access Networks (RAN) are gaining more interest from mobile carriers and governments. Yet, Open RAN networks have serious security challenges, especially in the RAN fronthaul where there are strict timing requirements. This paper proposes MACsec as an efficient data link layer security solution that can assist in meeting these challenges.
Why MACsec is a compelling security solution for Deterministic Ethernet networks and how Packaged Intellectual Property solutions can accelerate time-to-market for chip developers
This blog examines what separates truly automotive-grade Ethernet IP from generic implementations across functional safety, time-sensitive networking, security, observability, lifecycle management, and the integration disciplines that only become visible once a program is deep into development.
Software-Defined Vehicles (SDVs) are turning cars into distributed real-time computing platforms. Instead of dozens of standalone ECUs connected by a tangle of legacy field buses, we now see zonal controllers aggregating local I/O, centralized compute platforms running safety, mission critical software, and a service-oriented middleware layer stretching across the vehicle.
By offering a complete and standards-compliant portfolio of Ethernet IP and software, integrated with robust security solutions, Comcores enables OEMs and Tier 1s to design future-ready platforms with confidence.
This post explores critical considerations and solutions for implementing Ethernet switches tailored to industrial applications, emphasizing required features and cost-effectiveness.
