Study on Telemetry Data Authentication Protocol in Arms Control VerificationQiang, Huang, Fan, Yang 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The arms control verification activity is executed between countries, so various telemetry data will be remote-transmitted in the public signal channel and can be easily tampered. In order to secure this data’s authenticity and integrality, the paper has established a Multi-layer Data Authentication Protocol (MDAP) in which the key cryptographic technologies are digital signature and authentication. Meanwhile, overall evaluations of MDAP have been presented. We proved the MDAP is secure.

Can commercial satellite data aid in the detection of covert nuclear weapons programs?Lance, Jay Logan January 1993 (has links)
This research was conducted to determine the effectiveness of using commercial satellite data to detect covert nuclear weapons programs. Seven-band Landsat Thematic Mapper data covering the Pahute Mesa (an area within the United States Nevada Nuclear Testing Site), acquired on October 16, 1985, were analyzed to determine if underground nuclear test sites were spectrally distinguishable from the surrounding area. The analysis consisted of four steps: (1) analyzing the raw data, (2) manipulating the raw data through contrast stretching, filter application, matrix algebra, and principal components analyses, (3) identifying parameters that affect classification of underground nuclear tests and (4) selectively limiting parameters. The results of limiting parameters showed that a supervised classification of a signature created with a five-original-pixel seed of one representative, known test site provided an accurate classification of most known test sites. To further eliminate erroneous classification of roads and other areas of similar reflectance, these areas were seeded to create a second signature. This signature, whose spectral responses were different, was then used in a simultaneous classification. This classification further eliminated erroneous classification of non-test site areas, demonstrating that commercial satellite digital data can aid in the detection of covert nuclear weapons programs, in this case, underground nuclear testing. An application of the classification scheme used is proposed to confront a scenario in which a country seeks additional verification of another party's proposed violation of test ban treaties. / Department of Physics and Astronomy
