RFID Hacking is Easy as Picking up the Cell Phone

A cryptographer says that all a hacker needs is a cell phone to crack RFID tag encryption. Brings to light the concerns over the RFID embedded passports, don’t it? According to Adi Shamir (pictured), all he had to do was use “a directional antenna and digital oscilloscope to monitor power use by RFID tags while they were being read. Patterns in power use could be analyzed to determine when the tag received correct and incorrect password bits.� Apparently, quality RFID encryption seriously lacks due to sacrifices made by manufactures to get costs down to about $.05 a chip.
