Defcon Badge's Open Source Chip Doubles as an Inspectable Hardware Security Key
WIRED reports this year's Defcon badges contain Baochip-1x, a mostly open source microcontroller designed by Andrew 'bunnie' Huang that can be removed and used as a hardware security token. The chip is packaged so infrared light can shine through the silicon, allowing physical inspection against its published design — addressing supply-chain trust issues in chip manufacturing.
