Broadcom Implements MACsec in latest Quad 10GbE SFP+ PHY

Broadcom's latest 10 Gigabit Ethernet (10GbE) physical layer (PHY) transceiver includes support for the IEEE 802.1AE media access controller (MAC) security standard (known as MACsec) – a specification designed to safeguard connectionless data security, integrity and confidentiality for independent MAC protocols traveling between PC users and network servers and printers.



The new Broadcom BCM84756 40nm CMOS Quad SFI-XFI10GbE transceiver is the industry's first SFP+PHY supporting short reach (SR), long reach (LR), long reach over multi-mode fiber (LRM), and copper with full 802.1AE MACsec functionality.



Broadcom said its BCM84756 10GbE SFP-XFI transceiver with MACsec support is compliant with the IEEE 801.1AE standard. It is targeted for 10GbE links in data center and enterprise systems that carry high bandwidth traffic (such as financial information, engineering designs and scientific data), and require MACsec data integrity.



Unlike the Internet Protocol security (IPsec) standard that secures only IP data at the Ethernet level, the MACsec protocol effectively secures any type of data over Ethernet with the objective of authenticating the origin of data while protecting its integrity and confidentiality.
