RFID and the Singularity
I have just made it back from the week’s trip, and found that David Gilson had scouted out some good video for the SDR News YouTube collection.
I also just started on The Singularity is Near book from Ray Kurzweil, and just grabbed a few words in the first chapter introducing the idea of exponential growth in technology capability. For years and years, it looks almost linear. Then when it takes off, it blows the doors off of experience. That would extend to the capability of evil doers of all stripes, especially in RFID.
The passport RFID video is a good example of unintended consequences riding the technology curve. The problem is not on the technology, but on the ten year service life of the passport, in relation to the technology that is locked in place when the standard is set.
On a gentler curve, passport RFID could be expected to be reasonably secure, assuming that RFID probe and detection technology will be the same seven or eight years down the road. Real life might be different. Very different.
In my personal experience, I remember spending most of an afternoon in grad school in the 1970′s discussing fiber optics, as a curiosity. With losses of 30db/km in the best fibers, there was no way they would be useful. Long haul voice traffic was going to be on millimeter waveguide, and only needed on the highest density East Coast routes.
Likewise, the idea of a mobile handset radio chipset made from common CMOS silicon – instead of exotics like gallium arsenide – bordered on a joke, just seven years ago.
Don’t worry about RFID seven years from now. Worry about RFID detectors. The chip will be already in your passport – a good solid 2004 state of the art design.
So a passport with a ten year old technology
