New Zealander wants to sell completely open hardware random generator

A developer from New Zealand is working on a completely open hardware and software platform for a reliable random generator. The OneRNG must provide sufficient entropy through a radio receiver and an avalanche diode when generating random numbers.

According to developer Paul Campbell, a random generator where the user has full insight into the hardware and software used is necessary in the post-Snowden era to ensure that the numbers generated are as random as possible. The OneRNG uses two elements to generate random numbers: a so-called avalanche diode uses the generated noise, while a radio receiver increases the entropy based on collected noise.

According to the maker, the radio module filters out too strong signals to prevent an attacker from manipulating the operation of the OneRNG. The RF receiver can also be shielded from outside manipulation with a cover and the receiver ‘dances’ randomly through frequencies. Additional entropy can be generated via a so-called ‘whitening’ option. The OneRNG can be programmed, but the user must purchase an adapter for this. This should prevent hardware attacks via, for example, a USB connection.

The random numbers that the OneRNG generates can be used for, for example, encryption purposes and are accessible for example in Linux via the rngd daemon, responsible for supplying random numbers. Campbell informs The Register that he wants to present the OneRNG in December, after which sufficient money must be raised through a crowdfunding campaign for a market introduction. The device is expected to cost $50, or $40.
