GNU wannabee and Happy Hacking
I implemented safegcd256 for Gnuk. It uses signed 31-bit integers, and it does 19 iterations for p = 2**255 - 19.
In the computation of X25519, we need to compute the modular inversion at the last step to get the value of x in …
Q: I got another FST-01 with NeuG 1.0.5 installed. As I need Gnuk Token, I want to reflash. How can I install Gnuk without SWD debugger?
SWD debugger is not the absolute requirement, since NeuG supports firmware upgrade.
However, please note that the feature of firmware upgrade …
I wrote an article More Entropy, Please in June. Based on the article, we demonstrated a game in Debconf15 to promote randomness.
It's based on Monty Hall problem [1], and now we have three versions of the MEP game. I describe these three versions here in my own words and …

NeuG is an implementatio of True Random Number Generator, based on the sampling noise of ADCs (A/D converters).
It runs on STM32F103, and it outputs random bits at the rate of more than 80 kB/sec (kB = 1000-byte). The interface is USB, and it behaves as a device of …
