| Objective: ||Improve IA by conceiving, developing and demonstrating innovative PHY enhancements to current and near-term commercial wireless networking technologies, topologies, devices, and system.
|| Description: ||Wireless networks are becoming an important, and permanent, part of the Global Information Grid. In many cases, free space networking is replacing traditional wired networks because of lower costs, increased flexibility, smaller logistics tail and the advantages of mobility. However, unlike wired networks, limiting the physical access to a wireless network is an extremely challenging problem.
The objective of this effort is to improve overall information assurance (IA) by conceiving, developing and demonstrating innovative physical layer (PHY) enhancements to current and near-term planned commercial wireless networking technologies, topologies, devices, and systems. Current commercial networking technologies within the scope of this effort include those described by 802.11, 802.16, and Bluetooth standards. Near-term planned technologies within the scope of this effort include the anticipated follow-ons to the current technologies above. Areas that may be addressed include but are not limited to antennas, modulation, coding, RF watermarking, frequency control, and adaptive techniques. Simple "add-ons" to commercial devices are not as desirable as modifications that are highly integrated or can be done largely through additional/modified software/firmware. Benefits to be derived include increased data and network security, jam resistance, higher availability, increased integrity, stronger authentication, and non-repudiation while keeping cost low due to an efficient leverage of commercial technology.
|| ||PHASE I: Show proof-of-concept for proposed approach using design analysis, modeling, simulation, benchmarking, breadboarding, and/or experiments, etc. Demonstrate the potential utility and improvements to overall system IA. Develop preliminary commercialization and marketing plans.
|| || ||PHASE II: Construct a prototype of the design evaluated in Phase I. Conduct tests and demonstrations of the prototype to further prove the utility and specific improvements to overall system IA. Integrate the operation of the prototype with IA mechanisms operating at other layers of networking. Refine the commercialization and marketing plan.
|| ||DUAL USE COMMERCIALIZATION: Military application: In-garrison and deployed mobile, ad-hoc, and infrastructure wireless networks. Last mile connectivity to fixed and mobile units/individuals. Airborne network connectivity. Commercial application: High-assurance wireless network users, including financial, law-enforcement, security, first responders, e-commerce, etc.
