NXP RFID Cracked 111

Posted by kdawson on Tuesday April 01, 2008 @09:18PM from the that-was-easy dept.

kamlapati sends us to EETimes for news that the Chaos Computer Club in Germany and researchers from the University of Virginia have cracked the encryption scheme used in a common RFID chip, NXP's Mifare Classic. According to the article the device is used in many contactless smartcard applications including fare collection, loyalty cards, and access control cards. NXP downplays the significance of the hack, saying that that model of RFID card uses old technology and they do a much better job these days.

Using Tire Pressure Sensors To Spy On Cars 203

Posted by kdawson on Tuesday April 01, 2008 @05:21PM from the privacy-under-pressure dept.

AngryDad writes "Beginning last September, all vehicles sold in the US have been required to have Tire Pressure Monitoring System (TPMS) installed. An article up at HexView enumerates privacy issues introduced by TPMS, and some of them look pretty scary. Did you know that traffic sensors on highways can be adopted to read TPMS data and track individual vehicles? How about an explosive device that sets itself off when the right vehicle passes nearby? TPMS has been discussed in the past, but I haven't seen its privacy implications analyzed before. Fortunately the problem is easy to fix: encrypt TPMS data the way keyless entry systems do."

Yesss!!! The Art of Electronics is all you need to start with, in fact is "All You Need" (r). From there on just play yourself, experiment, read, burn capacitors, have fun!.

There are tons of more or less detailed projects in internet, ask Mr. Google

For a starter's microprocessor kit, I'll go fo Arduino it's cheap (22 euros plus shipping), all included (no need for a programer), and it's Open Source (well, that's slashdot, what else could you expect?;-).

If you're after audio look into DIY Audio & Video the cricket amp is a good starter project, and sounds nice (provided you do have an electric guitar). Or may be you prefer to assemble your own mp3 player or this other .

If you're after radio applications, ARRL is your place to go.

If you like robotics, the list is endless, try Kronos Robotics, DIY robotics (in UK), BEAM walkers , etc.

And for lots of ideas,as well of lot's of references, read Make , or just keep reading slashdot ;).
