Novel tamper-indicating protective devices
Several novel tamper-indicating devices, originally developed under DOE auspices for arms control applications, might be useful in nonproliferation. Some devices that have reached the laboratory prototype stage could provide specialized alternatives to established seals. As locks and cables, the following might be useful: (1) a brittle ceramic lock--impervious to toxic, radiation, and thermal extremes--interrogated for identification and continuity by ultrasonic means, (2) a flexible ceramic-fiber seal that also tolerates severe environments, (3) an ultrasonic smart-material strip seal, and (4) an RF-resonant coaxial cable, verified by radio frequency and microwave signals. To validate the identity of secured surfaces, joints, welds, and fasteners--two techniques are applicable: (1) the scanning electron microscope, which examines three- dimensional micron-level topography, and (2) the plastic-casting fingerprint, a simple low-cost technique, analogous to human fingerprinting. The techniques mentioned above have one or more of the potential advantages of low cost, immediate availability, security for large-area enclosures, application to hazardous environments, usability in the FSU, or suitability for covert use.
