ent3000: A new randomness testing suite for TRNG Makers generating in the sub 1 MB space. Successor to John Walker’s venerable ent. Please try it.

10 February, 2023

New year, new stuff. A piece highlighting the unseen dangers within America’s NIST organisation. And a related, very good read that seems frighteningly familiar.

14 March, 2022

Various re-jiggings of various things, but mainly to the 3 Golden Rules. And an analysis of the entropy coming from the Zenerglass ($ H_{\infty} = 5.5 $ bits/byte).

1 September, 2021

A solution to all of your life’s problems, using our un-biased quantum randomness powered life decision assistant. And some electro-mechanical details of the Zenerglass.

15 July, 2021

Further further electro-mechanical details of our Null Gamma Device, including a view of it running nicely.

10 June, 2021

PGP (GPG) key updated to outwit the Man.

5 June, 2021

Accurate entropy measurement of Photonic Instrument output using a novel chop and stack conditioning technique, resulting in $H_{\infty} = 7.9$ bits/byte or 34.5 46 kb/frame. And also a technique for mitigating the effects of ambient temperature changes.

13 April, 2021

Further mechanical details of our Null Gamma Device, including the I/O PCB. And Zener diode electrical behaviour, reaching the conclusion that $V_Z$ is pretty much unrelated to $H_{\infty}$.

30 December, 2020

An entropy analysis of our covert Type 3 cryptography kit (Mata Hari). We obtain 7.9 bits/byte $(\text{bias}, \epsilon = 2^{-9.5})$ of entropy at a rate of 4.4 kbits/s.
