TEMPEST -- Code Name For The Technology Used By The NSA To "Capture" The Brainwaves Of Those Being Targeted For Non Consensual Human Experimentation

From Wikipedia, the free encyclopedia :

TEMPEST is a codename referring to investigations and studies of compromising emanations (CE). Compromising emanations are defined as unintentional intelligence-bearing signals which, if intercepted and analyzed, disclose the information transmitted, received, handled, or otherwise processed by any information-processing equipment.

Compromising emanations consist of electrical or acoustical energy unintentionally emitted by any of a great number of sources within equipment/systems which process national security information. This energy may relate to the original message, or information being processed, in such a way that it can lead to recovery of the plaintext. Laboratory and field tests have established that such CE can be propagated through space and along nearby conductors.

The interception/propagation ranges and analysis of such emanations are affected by a variety of factors, e.g., the functional design of the information processing equipment; system/equipment installation; and, environmental conditions related to physical security and ambient noise. The term "compromising emanations" rather than "radiation" is used because the compromising signals can, and do, exist in several forms such as magnetic- and/or electric-field radiation, line conduction, or acoustic emissions.[1]

The term TEMPEST is often used broadly for the entire field of Emission Security or Emanations Security (EMSEC). The term TEMPEST was coined in the late 60's and early 70's as a codename for the NSA operation to secure electronic communications equipment from potential eavesdroppers[2].
