MAC-SeC-MG
The MAC-SEC-MG from CAST is a high-performance hardware MACsec IP core designed to provide robust security for 2-16.75 Gbps Ethernet networks. It fully implements the IEEE 802.1AE-2018 and IEEE 802.1AEbw standards, supporting GCM-AES and GCM-AES-XPN encryption modes with 128- and 256-bit keys. The core features a 128-bit wide data path and operates at line speed in full-duplex mode, ensuring low-latency and secure communication. It supports up to 64k security associations and multiple security channels and entities, making it suitable for both simple LAN deployments and complex WAN architectures. MAC-SEC-MG integrates easily with Ethernet MACs, including CAST’s Low-Latency eMAC, and can work alongside networking protocol stacks such as UDP/IP and TCP/IP. Its standardized interfaces and high configurability make it ideal for automotive, industrial, and IoT edge applications, providing reliable encryption, authentication, and integrity protection for sensitive Ethernet traffic.
