Stealth, in collaboration with the George Washington University and Georgetown University, was selected for (direct-to) Phase II funding for the DARPA SBIR program: Mobile Anti-Totalitarian HumaNets (MATH).  In this two-year effort, Stealth will develop a software system to support a phone-to-phone ad-hoc message transmission network. The Stealth solution, named MARATHON: Mobile Adaptive Relay Anti-Totalitarian Human Overlay Network, leverages cryptographic and networking techniques to provide improved user data-privacy and message-delivery success guarantees over the state-of-art HumaNet system.
