I thought this was a nice article on Flylogic’s Chris Tarnovsky in Wired magazine. If you watch the video, he goes through some of the steps that he uses to penetrate crypto smart card security.
Many of the fine chipshots featured on this blog are thanks to Chris’ master handiwork. Props to Chris and his mad skills!
Is this as tough as it sound?
