Compromising electromagnetic radiation: Challenges, threats and protection

Compromising Electromagnetic Emanations of Wired and Wireless Keyboards

Computer keyboards are often used to transmit confidential data such as passwords. Since they contain electronic components, keyboards eventually emit electromagnetic waves. These emanations could reveal sensitive information such as keystrokes. The technique generally used to detect compromising emanations is based on a wide-band receiver, tuned on a specific frequency. However, this method ma...

Electromagnetic Radiation and Epilepsy

People report adverse health symptoms which they attribute to the radiation of microwave signals from mobile phone and TETRA masts. The validity of such reports cannot be safely rejected, either on the grounds of current safety compliance, nor on the grounds that such symptoms cannot be replicated in laboratory experiments in search of a simplified mechanism. Biological effects caused by such e...

Electromagnetic radiation.

Electromagnetic fields (EMF) are ubiquitous in modern society. It is well known that exposure to strong fields can result in acute effects, such as burns; the mechanisms behind such effects are well established. There is, however, also a concern that long-term exposure to weak fields might have health effects due to an as-yet unknown mechanism. Because of the already widespread exposure, even s...

Network Security Threats and Protection Models

In a brave new age of global connectivity and e-commerce, interconnections via networks have heightened, creating for both individuals and organizations, a state of complete dependence upon vulnerable systems for storage and transfer of information. Never before, have so many people had power in their own hands. The power to deface websites, access personal mail accounts, and worse more the pot...
