  1. TEMPEST AND ECHELON A SEMINAR BY ROHIT RAJ ROLL NO-07130 VII TH SEM BRANCH – CSE I

  2. INTRODUCTION ECHELON • - Developed by National Security Agency of USA. • - A secret project to spy on people by tracing their message. • - To find out the terrorist activities across the globe. • Developed with the highest computing power connected through the • satellites all over the world. • Sniffing of messages over a network or any transmission media , even • wireless. • - Design: • * position intercept stations all over the world to capture all satellite, • microwaves , cellular and fiber-optic communications. • * process this information through the massive computer capabilities • of the NSA • * use advanced voice recognition and optical character recognition • (OCR) programs and look for code words or phrases known as • “echelon dictionary”

  3. TEMPEST • - Stands for “Transient Electro-Magnetic Pulse Emanation Standard”. • Main Theory • * any electronic or electrical device emits electromagnetic • radiations of specific key when it is operated. • Intercept electro-magnetic waves over the air. • It even sniffs signals emanating from computer screens(range of few • kilometers). • Captures signal through walls. • VDUs emit radiations when scanning up on vertical or horizontal • range beyond the screen.

  5. Need for an interception system • To keep track of spies and terrorists for preserving the • security of the country. • Also being used for purposes well outside its original • mission. • For political spying and industrial espionage.

  6. INSIDE TEMPEST: • TEMPEST is a short name referring to investigations and studies • of compromising emanation(CE). • Compromising emanations(CE) are defined as unintentional • intelligence bearing signals. • CE consists of electrical and acoustical energy unintentionally • emitted by a source. • The emanations occur as: • - text-relatedsignals through • a)common circuit element such as ground and power • supplies. • b)inductive and capacitive coupling. • - propagation of sound waves from mechanical and • electromechanical sound waves.

  7. Sources of TEMPEST signals a)Functional sources: -switching transistors, oscillators, signal generators synchronizers, line drivers and line relays. b)Incidental sources: -electromechanical switches and brush type motors.

  8. PROTECTION FROM TEMPEST ATTACK :- There are 3 methods to protect the computer from TEMPEST attack. • TEMPEST testing and selection of • appropriate devices. • TEMPEST fonts. • TEMPEST proof walls.

  9. PROBLEMS OF ECHELON AND TEMPEST:- • This system will not provide any privacy for our own people in home and abroad . It will not provide any security of data for the corporate world. • Every military secret is public to NSA and it’s allies so if anything goes wrong mass destruction will occur. • As stated , echelon can protect us from terrorist attack but we have to ensure that these systems are protected from intrusion. If not so then result will be hazardous. • Tempest equipments are only available in AMERICA and it is prohibited to be exported from there so that no terrorist will get these equipments .

  10. CONCLUSION • Tempest is the technology for spying from electronic • equipments without any physical contact. • Echelon is the vast network formed by NSA and its • allies all over the world to intercept the messages send • through any transmission media. • Nothing can be hidden from these systems. • Corporate firms are protecting there companies from • tempest attacks by the use of software and equipments • Unfortunately our INDIA does not have a tempest • equipment developed yet.

  11. Future scope of tempest&echelon • These can be used to empower intelligence agencies to do their job better than before. • As INDIA is not having a tempest equipment developed yet so we have to develop one for empowering our intelligence agencies and military agencies in order to protect our secret data from them.
