The integrated system proposed here by the DAT team includes the addition of access control points governed by DAT's strong authentication system. Such access control points involve minimum cost of deployment and should allow direct integration into existing legacy SCADA systems. The DAT system fuses 7 different credentials into an incalculable and continually dynamic authentication system. Although the specific operation of the system in the SCADA environment will developed in the course of the proposed SBIR, a preview of the specific credentials that must all be co-resident before access is authenticated (described below in further detail) include: 1. User specific information, such as biometrics. 2. The processor ID number on the user's authorized computer. 3. The volume ID number on the user's authorized ID number. 4. The DAT electronics ID number. 5. The LSDFTM historical table of physics based secrets (captured in the past by the user each time he logged in.) 6. The user's location, based on the use of the location awareness component of the DAT system to determine whether or not the user resides at a pre-approved location. 7. The correct sliding port target for access
