Coming up with a bulletproof way to secure your wireless network has been the challenge that has eluded boffins and continued to make many people cautious about making the switch to wireless. Hiding SSIDs, MAC filtering, WEP (64bit and 128bit) and WPA are now joined by... paint in the fight to protect wireless networks.
The University of Tokyo has developed a type of paint which contains (here comes the science bit) aluminium-iron oxide which when coated on walls apparently blocks wireless data from getting in or getting out of the room.
What do you think? Would you be interested in a security shielding you can slap on the walls, and would you redecorate in order to protect your wifi network from unwanted intrusions?
