New Hardware Solution Offers Cybersecurity Protection Well Before Malware or Virus Reaches Personal Computer

NEW YORK July 18, 2011

The approach offers considerable security advantages to consumers, explains Chao. "Our invention helps intercept viruses and malware at the earliest possible instance — before they even reach users’ computers — keeping networks running and protecting individual users," he said.

Effective DPI examines every packet entering a router switch. Its contents are compared against an ever-growing catalogue of known viruses or attack signatures. With millions of packets arriving each second, the process is often accomplished by a network of processors running parallel searches on portions of data packets — an approach that doesn’t scale well to high-speed traffic. Chao and Artan devised a scheme for consolidating the inspection process to a single node, compressing the catalogue of attack signatures to fit on one chip. This allows service providers to streamline their DPI strategy, using fewer resources without compromising efficacy or speed.  

With a prototype already developed, Chao and Artan are testing their solution with the goal of licensing the technology.
