Paranoia abounds! well maybe a bit – we are in a situation where we don’t trust our tools – especially our crypto tools – this project is an attempt to create a cheap open source entropy generator that’s open enough that one can verify and trust it. We’ve based our design on an existing platform – our Cheap RF system – mostly because it’s cheap to build, we had existing hardware, and had just finished bringing up a USB stack for it Our simple device is a USB stick, it is open source hardware, you can build your own, runs open source firmware – and you can physically open it to make sure that what’s inside is what you expect. With an external programmer you can also program it with your own firmware. We generate ~350kbits per second of entropy packaged at ~7.8 bits/byte – if you use the entropy data at a lower it accumulates and we quickly approach 8 bits/byte. [ ]
