TEMPEST
Hello, Group: Can somebody tell me what does TEMPEST stand for ? I know roughly what TEMPEST is about but I can't find out what these 7 letters represent either from books or internet. I suppose this is some kind of abbreviations, isn't it ? Regards Qu Pingyu - This message is coming from the emc-pstc discussion list.

TEMPEST
Hi Qu. You wrote: Can somebody tell me what does TEMPEST stand for ? I don't think that the letters stand for anything, rather it is a (British?) set of performance specs, standards, requirements essentially aimed at maintaing confidential communications. E.g. a Tempest monitor will not bleed video or z modulation signals that may be picked up by a sensitive receiver nearby. I've seen a demosnstration at an exhibition where the exhibitor of an 'Intrusive Monitor System' was able to dut up a screen display of all the screens around him at will, just by homing in on their timebases and video signals with a highly directional antenna. TEMPEST, seeks to eliminate this leak of 'intellligence'. It's not only monitors, but data comms, RF, printers, anthing which could radiate, or conduct, data to an interested and well equipped third party. At least I think that's what it is. :-) Chris Dupres Surrey UK. - This message is coming from the emc-pstc discussion list.

RE: TEMPEST - the whole nine yards
A review of TEMPEST Legal Issues Notice: I recieved this document a bit chopped up, while it is complete thetext is mismatched with the references, and several references appear to be missing. In the novel 1984, George Orwell foretold a future where individuals had no expectation of privacy because the state monopolized the technology of spying. The government watched the actions of its subjects from birth to death. No one could protect himself because surveillance and counter- surveillance technology was controlled by the government. This note explores the legal status of a surveillance technology ruefully known as TEMPEST[2]. Using TEMPEST technology the information in any digital device may be intercepted and reconstructed into useful intelligence without the operative ever having to come near his target. The technology is especially useful in the interception of information stored in digital computers or displayed on computer terminals. The use of TEMPEST is not illegal under the laws of the United States[3], or England. Canada has specific laws criminalizing TEMPEST eavesdropping but the laws do more to hinder surveillance countermeasures than to prevent TEMPEST surveillance. In the United States it is illegal for an individual to take effective counter-measures against TEMPEST surveillance. This leads to the conundrum that it is legal for individuals and the government to invade the privacy of others but illegal for individuals to take steps to protect their privacy. I. INTELLIGENCE GATHERING Spying is divided by professionals into two main types: human intelligence gathering (HUMINT) and electronic intelligence gathering (ELINT). As the names imply, HUMINT relies on human operatives, and ELINT relies on technological operatives. In the past HUMINT was the sole method for collecting intelligence.[4] The HUMINT operative would steal important papers, observe troop and weapon movements[5], lure people into his confidences to extract secrets, and stand under the eavesdrip[6] of houses, eavesdropping on the occupants. As technology has progressed, tasks that once could only be performed by humans have been taken over by machines. So it has been with spying. Modern satellite technology allows troop and weapons movements to be observed with greater precision and from greater distances than a human spy could ever hope to accomplish. The theft of documents and eavesdropping on conversations may now be performed electronically. This means greater safety for the human operative, whose only involvement may be the placing of the initial ELINT devices. This has led to the ascendancy of ELINT over HUMINT because the placement and monitoring of ELINT devices may be performed by a technician who has no training in the art of spying. The gathered intelligence may be processed by an intelligence expert, perhaps thousands of miles away, with no need of field experience. ELINT has a number of other advantages over HUMINT. If a spy is caught his existence could embarrass his employing state and he could be forced into giving up the identities of his compatriots or other important information. By its very nature, a discovered ELINT device (bug) cannot give up any information; and the ubiquitous nature of bugs provides the principle state with the ability to plausibly deny ownership or involvement. ELINT devices fall into two broad categories: trespassatory and non-trespassatory. Trespassatory bugs require some type of trespass in order for them to function. A transmitter might require the physical invasion of the target premises for placement, or a microphone might be surreptitiously attached to the outside of a window. A telephone transmitter can be placed anywhere on the phone line, including at the central switch. The trespass comes either when it is physically attached to the phone line, or if it is inductive, when placed in close proximity to the phone line. Even microwave bugs require the placement of the resonator cone within the target premises.[7] Non-trespassatory ELINT devices work by receiving electromagnetic radiation (EMR) as it radiates through the ether, and do not require the placement of bugs. Methods include intercepting[8] information transmitted by satellite, microwave, and radio, including mobile and cellular phone transmissions. This information was purposely transmitted with the intent that some intended person or persons would receive it. Non-trespassatory ELINT also includes the interception of information that was never intended to be transmitted. All electronic devices emit electromagnetic radiation. Some of the radiation, as with radio waves, is intended to transmit information. Much of this radiation is not intended to transmit information and is merely incidental to whatever work the target device is performing.[9] This information can be
Re: 60Hz in PC Monitor
Hi Rick, we experienced similar problems in our company. The magnetic field may be produced in two ways: 1. Power cable in the wall. The sum of the currents is not zero because a (high) percentage of the current flows to protective ground (multiple bonding or capacitors, mainly in power line filters (sic!!) 2. The current you miss in the cables flows back to the source (another bonding point) through the steel in the wall. green yellow PE conductors etc. They cause a magnetic field. We measured the field intensity but even after having the figures we could not eliminate the cause. Try following (helps only if fields are not strong) Set the vertical frequency to 90 Hz (as far as possible from 60 Hz, 120 Hz, 180 Hz etc.). Thus the perceived frequency of disturbance would be 30 Hz, to high for normal eyes. You will perceive only a slight unfocus. If it does not help, try moving the monitor to another position, rotate the monitor or get another monitor ( like Nokia) If this does not help you'll have to by some very expensive and very ugly magnetic shielding (looks like a telephone cell). We bought about 60 in our company.

Re: 60Hz in PC Monitor
Rick, Might the filtering of the 60Hz out of the power supplies be poor and worse as the CRTs warm up? Remember, they're cold when you move them elsewhere for a test. Alternatively, might the 60Hz fluorescent lighting falling on these monitors interact differently with the screen refreshing than on other monitors in such a way as to cause visual effects? Just thoughts. Look for the simple solutions before you blame the Martians.

RE: 60Hz in PC Monitor
I experienced that same problem at the last company I worked for. There was a circuit breaker panel one the same wall that the 2 monitors were located. We wound up re-arranging the area slightly to ensure that the monitors were away from that wall. It wasn't conducted through the line cord. My thought was that it was possibly an immunity problem with those two monitors in particular and we switched monitors, but that wasn't it. It was merely a matter of physical proximity. We never pursued any fixes? other than moving the monitors. John A. Juhasz Product Qualification Compliance Engr.
