[Cryptech Tech] Google's project vault

[Bernd Paysan]

Google has presented a crypto card project, and at the same time has checked 
in a repository on GitHub:

Apache license, the hardware SoC is Verilog, so if we find something 
interesting, we could use it.  And of course we can have fun reviewing it ;-).

The TRNG is xor-based free-running combinatorical logic, with one inverter to 
start it up.  It doesn't follow the same guidelines of rigid inspectability 
that I used for my ring oscillator submission to the cryptech project 
(inspectability means including measurement of jitter and bias of each 
individual ring oscillator).

However, I think I was the only one who actually did measure the jitter of the 
ring oscillators, and the current design doesn't allow end users to run that 
test, so we fail on that, too ;-).
