Dutch RFID Transit Card Hacked

2008-01-21 06:35:43 by schneier in Schneier on Security
 
...circuitry. By studying the circuitry, they were able to deduce the secret cryptographic algorithm used by the chip. While this alone does not break the chip, it certainly gives future hackers a stepping stone on which to stand. On Jan. 8, 2008, they released a statement abut their work Most of the links are in Dutch; there isn't a whole lot...

Kn1ghtl0rd and Lowtek Mystik's RFID 2.0 PhreakNIC Presentation

2007-09-21 05:05:54 by Editor in Irongeek's Security Site
 
...circuitry of an RFID tag and what it takes to make them operate more consistently. The presentation will also cover actual tag data and coding schemes with standardization including EPC Gen 2 and other ISO standards such as PayPass RFID enabled credit cards. There will be reader/writer demonstrations as well as other proof of concept...

Your Brain on Fear

2008-01-09 06:10:54 by schneier in Schneier on Security
 
...circuitry makes it more powerful than the brain's reasoning faculties. The amygdala sprouts a profusion of connections to higher brain regions -- neurons that carry one-way traffic from amygdala to neocortex. Few connections run from the cortex to the amygdala, however. That allows the amygdala to override the products of the logical,...

Detecting Nuclear Weapons Using the Cell Phone Network

...circuitry and would not add significant bulk to portable electronic products, Fischbach said I'm not convinced it's a good idea to deploy such a system, but I like the idea of piggy-backing a nationwide sensor network on top of our already existing cell phone infrastructure

Got Entropy ?

2008-04-02 02:55:47 by Erik T. Heidt in Art of Information Security
 
...circuitry I think this is a pretty strong RNG, and I have provided an interface for pulling just the values Also, I have written a script ( getEntropy.sh ) that will pull Entropy from the service and seed it into /dev/random on Linux Results from ENT Here are results, from a sample run of the Got Entropy, analyzed by ENT ( A Pseudorandom...

Designing Processors to Support Hacking

2008-04-24 13:52:33 by schneier in Schneier on Security
 
...circuitry; we show that an attacker, rather than designing one speci?c attack, can instead design hardware to support attacks. Such ?exible hardware allows powerful, general purpose attacks, while remaining surprisingly low in the amount of additional hardware. We show two such hardware designs, and implement them in a real system. Further,...
