Traditionally, bypassing security protection and extracting secret from physical devices requires decapsulation of the chip package, and using UV rays, laser beams, ion beams, microprobes, electronic microscopes to interference with and modify the circuity. This requires a high budget of ~10,000+ dollars, and usually prohibitively expensive enough to stop most attackers.

Improvements of practical side-channel attacks and non-invasive fault-injection attacks is really disturbing. In the end, there is nothing to keep my private key from being extracted out of the smartcard...

Credit card decaping doesn't seem to be ceasing due to that

Power glitching has been known for a long time to defeat microcontroller copy protection, and so is the use of EMP; but the trick is to not induce latchup, which will cause permanent physical damage.

Another common trick is clock glitching.

Seems similar to how the Xbox 360 was eventually hacked, but using electromagnetic pulses rather than invasive contact wires.

Would you kindly provide link to the research or some reference? Really would love to read up on that.

Google "Reset Glitch Hack" or "JTAG hack".

Wonder why he removed it.
