re tempest in article apr infodev cam ac uk rja cl cam ac uk ross anderson writes i m afraid this doesn t work either we can pick up laptop screens without any problem most of the so called low radiation monitors are also useless the description turns out to a marketing assertion rather than an engineering one we thought there might be a market for a monitor which was not as hugely expensive as the military tempest kit but which was well enough shielded to stop eavesdropping using available receivers we built a prototype it works and it s still sitting on my lab bench commercial interest was exactly zero in the absence of open standards a monitor which really is low radiation and costs dollars more can t compete against a monitor which just claims to be low radiation and whose only extra cost of production is the pretty blue sticker on the box ross i heard somewhere can t name the source that tempest does not necessarily pick up just crts but it can pick up emissions from almost any chip if that is true the kind monitor would not make any difference becuase everything on the screen can be picked up from the video controller can anybody verify or refute this angel foghorn leghorn coe northeastern edu btw these are my opinions and not that of any other entity my god its full of stars dave i don t know about you but we ve got company epidemic
