VirnetX Receives European Security Patent

SCOTTS VALLEY, Calif., Dec. 2, 2010 /PRNewswire/ -- VirnetX Holding Corporation (NYSE Amex: VHC), an Internet security software and technology company, today announced that it has been granted Patent # EP99958693 by the European Patent Office.  The patent for network protocol for secure communications builds upon the Company's important patent portfolio that address critical communication security needs of large enterprises, managed service providers and technology OEMs.

The methods in this patent are used to create a special kind of Virtual Private Network (VPN). This VPN not only includes the normal authentication and privacy, but also includes a stealth feature. This stealth feature is achieved by randomly changing the IP packet addresses on a packet-by-packet basis. Methods are described that enable the computers at each end of the VPN to use cryptographic techniques and synchronize the random address sequence. Third party observers cannot predict the sequence and the packets appear to be unrelated and not part of the same network connection. 

"We are very pleased with the issuance of this patent," said Dr. Robert Short lll, VirnetX Chief Technical Officer and Chief Scientist and one of the inventors of the patent.  "The technologies described in this patent were originally developed for protecting National Security assets, but we believe that they could prove equally important for protecting extremely valuable commercial assets.  The issuance of this patent also signifies VirnetX's ongoing commitment to R & D with focus on the challenges facing both national and international security."
