Vitesse Integrates MACSec into GE & 10GE PHYs for End-End Layer 2 Encryption

Vitesse Semiconductor introduced the first PHY transceivers to integrate MACSec technology for end-to-end, Layer 2 network security.

The new Vitesse SynchroPHY Gigabit Ethernet (GE) and 10GE devices enable network-wide Layer 2 MACsec encryption and preserve nanosecond-level IEEE 1588v2 accuracy.

Vitesse said this new paradigm of establishing Layer 2 encryption end-to-end, rather than link-by-link as is now the case, will prove to be especially useful for cloud services, mobile backhaul and other high-value communications. Until now, MACsec PHYs have traditionally been limited to link-based box-to-box applications primarily within cloud service data centers

Key elements of the Vitesse solution include:

VeriTime: the industry’s highest accuracy IEEE 1588v2 Precision Time Protocol

Intellisec: the industry’s first PHY technology to enable IEEE 802.1AE MACsec encryption.  Intellisec offers 256-bit encryption support, versus the 128-bit encryption typically today.

 “Vitesse’s approach enables a paradigm shift in mobile, cloud, and other critical infrastructure networks,” said Richard Interrante, product marketing director at Vitesse. “VeriTime delivers the industry’s de facto highest accuracy IEEE 1588v2 network timing and now we’ve again moved beyond our competitors with this latest generation incorporating Intellisec. Delivering low latency security while preserving network synchronization simply isn’t possible with traditional link-based MACsec technology. Vitesse is first to do this, making network-wide Layer 2 security a realistic and affordable option for carriers and other cloud providers.”

Sampling is underway.

  • GE PHYs with copper and fiber media support 
  • 10GE PHYs
    -  VSC8582-10: 2-port SGMII/QSGMII GE PHY
    -  VSC8584-10: 4-port SGMII/QSGMII GE PHY
    -  VSC8490-10: 2-port WAN/LAN/Backplane RXAUI/XAUI to SFP+/KR 10GE PHY
    -  VSC8491-10: 1-port WAN/LAN/Backplane RXAUI/XAUI to SFP+/KR 10GE PHY
