Tempest and Echelon

.doc   tempest and echelon report.doc (Size: 385.5 KB / Downloads: 23)


The notion of spying is a very sensitive topic after the September 11 attack of Terrorists in New York. In the novel 1984, George Orwell foretold a future where individuals had no expectation of privacy because the state monopolized the technology of spying. Now the National security Agency Of USA developed a secret project and implimentation to spy on people for keep tracing their messages to make technology enabled interception to find out the terrorist activities across the globe, named as Echelon. Leaving the technology ahead of the any traditional method of interception.
The secret project and implimentation Developed by NSA (National Security Agency of USA) and its allies is tracing every single transmission even a single of keyboard. The allies of USA in this project and implimentation are UK, Australia, New Zealand and Canada. Echelon is developed with the highest computing power of computers connected through the satellites all over the world. In this project and implimentation the NSA left the wonderful method of Tempest and Carnivores behind.
Echelon is the technology for sniffing through the messages sent over a network or any transmission media, even it is wireless messages. Tempest is the technology for intercepting the electromagnetic waves over the air. It simply sniffs through the electromagnetic waves propagated from any devices, even it is from the monitor of a computer screen. Tempest can capture the signals through the walls of computer screens and keystrokes of key board even the computer is not connected to a network. Thus the traditional way of hacking has a little advantage in spying.


Interception of communications is a method of spying commonly employed by intelligence services, whereas there can now be no doubt that the purpose of the system is to intercept, at the very least, private and commercial communications, and not military communications, although the analysis carried out in the report has revealed that the technical capabilities of the system are probably not nearly as extensive as some sections of the media had assumed.

The Need for an Interception System

Interception of messages is the major work for the intelligence agencies all over the world, to keep track of the spies and terrorists for preserving the security of the country from the leaking of sensitive documents and the terrorist attacks. By the work of the intelligence agencies the government is ensuring the security of the state. For that we have to enable our intelligence agencies with modern technologies like USA. For that we must setup an interception system. While developing this we have to consider about the privacy of common people and industrial organization.
The targets for the ECHELON system developed by the NSA are apart from directing their ears towards terrorists and rogue states; ECHELON is also being used for purposes well outside its original mission. In America the regular discovery of domestic surveillance targeted at American civilians for reasons of “unpopular” political affiliation or for no probable cause at all in violation of the First, Fourth and Fifth Amendments of the Constitution of America– are consistently impeded by very elaborate and complex legal arguments and privilege claims by the intelligence agencies and the US government. The guardians and caretakers of their liberties, their duly elected political representatives, give scarce attention to these activities, let alone the abuses that occur under their watch. The other ECHELON targets are political spying and industrial espionage.


TEMPEST is a short name referring to investigations and studies of compromising emanations (CE). Compromising emanations are defined as unintentiorial intelligence-bearing signals which, if intercepted and analyzed, disclose the national security 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 "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, (signal and power) or acoustic emissions.

Technology behind the TEMPEST: -

We discussed that the TEMPEST uses the electromagnetic waves propagated from the electronic devices intentionally or non intentionally. For receiving the texts or data at the other end we have to screw up to a specific frequency range and just listen or replicate the data at the other end. Tempest is the technology, which can reproduce what you are seeing in your monitor, what you are typing in your keyboard from a couple of kilometres away. It traces all electromagnetic radiation from the victim’s monitor, keyboard, even pc memory and hard disk, and then it reproduces the signals. By using this technology it is possible to intrude (only listening) in to a person’s computer from a couple of kilometres away, even it is a computer which is not “Networked” and enables the intruder to hack without any connection to the victim’s computer.


ECHELON stands for NSA’s (National Security Agency of America) secret Global Surveillance System developed for intercepting the messages over the world. As said in the Medias NSA is No Such Agency, but it is not the truth. This massive surveillance system apparently operates without the oversight of either Congress or the courts. Shockingly, the NSA has failed to adequately disclose to Congress and the public the legal guidelines for the project and implimentation. Without those legal guidelines and an explanation of what they allow and forbid, there is no way of knowing if the NSA is using Echelon to spy on Americans in violation of federal law. In April 2000, the House Intelligence Committee held a hearing to deal with credible reports that suggest Echelon is capturing satellite, microwave, cellular and fiber-optic communications worldwide. The House Intelligence Committee intended the hearing to help ensure that ECHELON does not circumvent any requirement in federal law that the government obtains a warrant from a court before it eavesdrops on a conversation to, from, or within the United States.

Espionage methods

Espionage involves gaining access to information which the holder would rather protect from being accessed by outsiders. This means that the protection needs to be overcome and penetrated. This is the case with both political and industrial espionage. Thus the same problems arise with espionage in both fields, and the same techniques are accordingly used in both of them. Logically speaking there is no difference; only the level of protection is generally lower in the economic sphere, which sometimes makes it easier to carry out industrial espionage. In particular, businessmen tend to be less aware of risks when using imperceptible communication media than does the state when employing them in fields where security is a concern.

Processing of electromagnetic signals

The form of espionage by technical means with which the public are most familiar is that which uses satellite photography. In addition, however, electromagnetic signals of any kind are intercepted and analysed (.signals intelligence, SIGINT). In the military field, certain electromagnetic signals, e.g. those from radar stations, may provide valuable information about the organisation of enemy air defences (.electronic intelligence, ELINT). In addition, electromagnetic radiation which could reveal details of the position of troops, aircraft, ships or submarines is a valuable source of information for an intelligence service. Monitoring other states, spy satellites which take photographs, and recording and decoding signals from such satellites, is also useful.
