Research Institution
The Phase II technical proposal describes strategies for system level implementation of our novel multipath encryption scheme for location specific authentication. Brief discussion of VHF frequency domain channel sounding approach to extract wireless channel multipath for geo-specific encryption is provided. Convincing experimental results are presented to prove the channel reciprocity concept for Line of sight (LOS) and non-LOS terrains. The technology can be integrated on existing SINCGARS platform for long range authentication. Building on these Phase I results, we lay out our phase II plan. Primary tasks involve SCA compliant waveform generation and testing on the JTRS SCA platform, Ground measurements with radios generating JTRS compatible waveforms and airborne measurements for validation of the multipath encryption technique. Measurements will be coupled with comprehensive simulations to model ground, airborne propagation channels, and aircraft dynamics to understand system level constraints. A complete description of the tasks, along with the time line is included in the report. The ultimate goal of the Phase II effort is integration of our technique with the JTRS AMF cluster of radios. Additional technical contributions will be provided by Raytheon Network Centric Systems and Virginia Tech, who are our prime sub-contractors.
