New controller IP core for secure data

06 March 2023

Data security is one of the most important issues in today's digital age. Increasing system attacks and cybercrime make it necessary to secure data in new ways. Recognising this the Fraunhofer Institute for Photonic Microsystems IPMS has developed the MACsec Controller IP-Core, which implements the latest Ethernet security standards.

It provides authentication, integrity and encryption of data between different nodes of a Local Area Network (LAN).

Fraunhofer IPMS has been developing and licensing IP cores to companies from a wide range of industries around the world for 20 years. Increasing digitalisation and the resulting growing danger of cyber-attacks make it necessary to continuously adapt and further develop IP cores. This is the only way to ensure data security in the future.

The latest controller IP core Media Access Control Security (MACsec) implements the Layer 2 security standard specified in IEEE 802.1AE. “MACsec protects Ethernet connections at the second layer of the OSI model by using a combination of authentication, encryption, and integrity protection to ensure that only authorised nodes communicate on the network, that traffic remains confidential, and that data integrity is ensured," said Dr. Frank Deicke, Division Director DCC at Fraunhofer IPMS.

The MACsec can be used with Fraunhofer IPMS' LLEMAC IP core, as well as any other Ethernet MAC IP core, and in standalone mode. Due to the platform independence an easy system integration is possible, so that the MACsec can be integrated on every FGPA as well as ASIC.
