In http://cryptome.org/nacsem-5112.htm the Censors allow: 6.2.2 (U) Signal Measurement Standards 6.2.2.1 (U) AM Generators 6.2.2.1.1 (U) Requirements 6.2.2.1.2 (U) Calibration 6.2.2.2 (U) FM Generators 6.2.2.2.1 (U) Requirements 6.2.2.2.2 (U) Calibration 7.6.2 (S) Specific RED Equipment Operation During AM and FM Tests 7.6.2.1 (S) Test for Plain-Text Emanations 7.6.2.2 (S) Test for Key or Keying Variable Emanations I think 7.6.2 (and the rest of the doc) support the hypothesis that NONSTOP compliance means that a device does not leak when you inject (external, RF) signals into it, esp. during operation. This would be in addition to TEMPEST compliance which assures only that the device in isolation does not spill the beans. As usual, the truly classified stuff would be the details ---how many watts, how much FM mod, etc. NONSTOP would seem to be related to the tests that RNG builders put themselves through, trying to see how big that White Van must be to mess with their RNG. Together TEMPEST/NONSTOP seem to be a crypto slant on the FCC's "accept all evil", "emit no evil" rules for interference in consumer devices. ====== "All the normalities of the social contract are abandoned in war" Jack Valenti MPAA pres LATimes (on Kerry's war crimes)
