Silicon Superconductors 141

Diana writes "Physicists at CNRS have demonstrated superconductivity in silicon, the element long known for its semiconducting properties. High doping is the key — by substituting 9% of the silicon atoms with boron atoms, it was found that the resistance of the material drops sharply when cooled below 0.35 K. A small increase in the transition temperature is likely with further work."

The standards (sorry - I am only familiar with one side of the UWB arena) define security measures:
1. All traffic is encrypted.
2. There are anti-replay counters.
3. There are multiple-key exchanges.
4. A method for ensuring devices can't be "impersonated".

Don't get me wrong - I don't believe these measures are going to help. The only thing that's going to ensure your data's safety from prying eyes, is if you are sufficiently paranoid.

It's like the thing with viruses - you put an anti-virus on your PC, and think it's OK? I don't. I admit it - I am paranoid, but I know I am not paranoid enough.

I say - paranoia will keep you safe ;-)
