This is one of the Clay Mathematics Institute's seven Millennium Prize problems so the author may be rewarded well for his effort.

How would you protect against such attacks? Even if you can prevent this in your home by setting a shielded environment, how would you prevent your next door office mate from listening to your keyboards? That means that if you are a senior executive member in your company, a junior staff in a cubicle knows your bank passwords!

Very soon, we will see a class of "secure keyboards" surfacing in the market.

Most people are familiar with resistors, inductors and capacitors which are three basic passive circuit elements. Using complex mathematics, Leon Chua in 1971 predicted the existence of fourth element which he named memritsor. Until recently, not many people knew how to make one. Senior Fellow R. Stanley Williams at HP has not only shown how to make one but also explains how it can be used in nano-circuitry in this article (Information Week
