Patent number: 8711688Abstract: Network communications face security issues including traffic flow analysis attacks. Such attacks include deduction of information about networks through analysis of transmitted traffic volume or statistics, even if the traffic is encrypted. For example, an adversary may deduce operational information from traffic volume, or its timing. Described herein are security techniques that can provide transmission security with an obfuscating “cover” signal for any contention-based multiple access system by employing signal interference cancellation techniques, but are not so limited. The cover signal is transmitted on the same frequency band used by terminals on the network. Using “known-signal” and/or self-interference cancellation techniques, the cover signal can be removed by authorized terminals that have appropriate cover signal information and timing synchronization.Type: GrantFiled: April 22, 2011Date of Patent: April 29, 2014Assignee: VIASAT, Inc.Inventors: Edward Smith, Donald Wilcoxson, Shay Har-Noy

Patent number: 8238284Abstract: Techniques for enabling broadband data rates at mobile terminals in a beyond-line-of-sight communication system are disclosed. Forward link time-diversity transmission methods and a time-diversity transmitter based upon blockage characteristics are provided. The transmitter optionally supports selective time-diversity and can operate at Ku-band or higher frequencies. A forward link time-diversity receiver and methods for receiving a forward link time-diversity signal are also disclosed. The forward link time-diversity receiver optionally provides low-jitter or low-delay characteristics. A return link transmitter and return link transmit methods which avoid blockages are also disclosed. The return link transmitter can include a signal presence detector and blockage prediction filter.Type: GrantFiled: October 22, 2007Date of Patent: August 7, 2012Assignee: Viasat, Inc.Inventors: Donald Wilcoxson, John O'Neill, Daniel Chester, Brian Sleight
