ZILOG and Icon Labs Announce Secure ZGATE Ethernet Bridge Technology and Module Reference Design

Zilog®, a wholly-owned subsidiary of IXYS Corporation (NASDAQ:IXYS), and a pioneer in MCU design and production, announces the introduction of the ZGATE Security Bridge Reference Design, a joint technology solution utilizing Icon Labs’ Floodgate technology. Together, Zilog and Icon Labs have produced a microcontroller featuring an embedded firewall that provides a critical layer of security for networked devices. The new ZGATE Security Bridge Reference Design is a clever new approach that utilizes an embedded microcontroller and levels of protection that go beyond typical firewall security to allow smart devices to resist malevolent attacks.

Based on Zilog’s eZ80Acclaim and embedded with Icon Labs’ Floodgate™ technology, the new ZGATE Ethernet bridge and reference design module, will help reduce the incidence of security breaches for many types of products in defense, telecommunication, utility, transportation, medical and industrial applications.

“Zilog and Icon Labs cooperated on this innovative MCU-based solution to keep in step with the world’s need for stronger security solutions across many embedded applications,” said Steve Darrough, Zilog’s VP of Marketing. “ZGATE is the first and only embedded hardware communication solution that can protect connected devices from the growing number of internet-based threats.”

“Icon Labs’ Floodgate technology provides protection from internet-based threats by controlling which packets the embedded device is allowed to process,” said Alan Grau, President of Icon Labs. “Encryption and authentication may protect a device from a hacker trying to access the device, but Floodgate prevents the hacker from ever connecting. Floodgate’s filtering engine can block denial of service attacks, packet floods, port scans, or other Internet-based threats.”
