Transient Electromagnetic Pulse Emanation Standard (TEMPEST) is the US standard defining the amount of electromagnetic radiation that a device may emit without compromising the information it is processing. In the US it not illegal to posess TEMPEST-surveillance equipment but it is illegal to take appropriate counter-measures to prevent surveillance. The US government has refused to release details of its TEMPEST research and has restricted the dissemination of independent research by classifying it. The US Drug Enforcement Agency (DEA) makes use of TEMPEST secured electronics and computers as they believe that the drug cartels may possess surveillance equipment. I am interested in gathering comments on the social, legal, ethical, and technical aspects of use of TEMPEST surveillance equipment in the US and Europe with the aim of including it in a discussion of the threats to computer/digital systems. Please reply by E-mail. I will provide a summary to anybody who requests one. thanks, - Rob Jackson (more information on TEMPEST can be found in the paper "Eavesdropping On the Electromagnetic Emanations of Digital Equipment: The Laws of Canada, England, and the US" by Cristopher Seline - available on FTP from csrc.ncsl.nist.gov)
