Transcript

{{transcript}}

Entropy sources

  • mashed keyboard to generate random string
  • bytes from /dev/urandom from machine ...
  • webcam
  • audio input
  • Geiger counter
  • random words from random books
  • asked people for random numbers / words

Side channel defenses

  • Left other processes running
  • Didn't use swap space
  • Ran the software on secure hardware
  • Didn't tell anyone except coordinator about participation in advance

Other defenses

  • Disconnected network during generation of contribution
  • Rebooted with airgap before generation of contribution
  • Full disk encryption
  • Put the machine in a Faraday cage
  • Used multiple machines and randomly picked the result of one of them
  • Ensured no one could see the screen

Post processing

  • Filled up memory with memtester
  • Rebooted the machine
  • Power-cycled the machine
  • Wiped the storage drive
  • Destroyed the machine after (!)

Sharing of results

I intend to share the files:

  • via IPFS using multisetups
  • via GitHub PR
  • via magic-wormhole
  • via INSERT CLOUD STORAGE HERE
