SWAP/VAWCS, A Voice Authenticated Wireless Communication System that Uses an Innovative Adaptive communications Protocol

With the advent of satellite telephone services, it is now feasible to provide secure voice communication to any location on Earth. In a Phase I SBIR for AFRL, Black & Ryan Engineering (BRE) developed VAWCS (Voice Authenticated Wireless CommunicationSystem), a computer model of a Communications Waveform, combining Voice Authentication, Speech Compression, Encryption, and Forward Error Correction for narrowband wireless communication over a SATCOM Channel. BRE now proposes a Phase II SBIR project to: ¿ Formally specify and initially implement a new adaptive packetization protocol called SWAP (Secure Wireless Adaptive Protocol) designed to: A. Enhance the flexibility of VAWCS, allowing users to selectively specify features for flexible communication, and B. Serve as a generalized adaptive communication framework for the Air Force's Joint Battlespace Infosphere (JBI) Program. ¿ Implement the VAWCS Waveform Model on Motorola's Software Defined Radio / Wireless Information Transfer (SDR / WITS) platform, using the WITS 4800 Baud satellite communications (SATCOM) Radio Waveform Data Mode. BRE will:1. Develop streaming data CORBA interfaces between VAWCS components,2. Port the VAWCS model to the WITS platform,3. Integrate an initial implementation of the SWAP Protocol for VAWCS, and4. Test the system in the presence of simulated/real background and channel noise.
