Security for Wireless Handheld Devices

The DAT system brings location awareness and physics-based random numbers to the wireless security and access control environment. It uses a small passive RF device to capture a signature from a location, and then employ the signature in the future to determine where a person is when he logs in. The RF module also extracts a random number from the environment whose value is truly not predictable (think of Brownian motion). The system employs these physics based random numbers as part of a challenge response process to establish who is doing what from when, where, and on what device, and are used to create dynamic encryption keys that change with each person and with each session. This project will design, build and deploy into an Army facility a limited size secure wireless system employing the physics based elements studied in Phase I. This should be used for testing and red-teaming studies by Army. The system will fuse 7 different credentials into an incalculable, continually changing authentication system. DAT believes that a physics based authentication system is ideally suited to an immediate, revolutionary and significant strengthening of wireless network systems with minimal impact on costs and current method of operation.
