This contribution presents a preliminary investigation on the possibility of eavesdropping, i.e., of extracting information by exploiting the electromagnetic field radiated in the vicinity of a power line communication (PLC) network. This kind of problem is usually known in the electromagnetic compatibility area under the codename TEMPEST. Electromagnetic field measurements were carried out in ...

Recently, due to the widespread use of computers, text-based communication methods, such as e-mail and chat, have attracted a great deal of attention. If pianists can apply their musical expressions to the text input, they can input texts with their own emotion richly. Therefore, the goal of our study is to construct TEMPEST (TExt input and Musical PErforming SysTem) that is a text input system...

A working personal computer (PC) and/or a PC display monitor usually produce unintentional electromagnetic fields. It has been known that the information from a video display unit could be reconstructed by intercepting such emissions at a distance. Proper measures are needed to prevent information leakage against such eavesdropping, which are often collectively called “TEMPEST”. We have studied...
