NeuG is an implementation of True Random Number Generator based on quantization error of ADC of STM32F103. It is basically intended to be used as a part of Gnuk, but we also have standalone USB CDC-ACM version (you can get random stream from /dev/ttyACM0). Standalone version is useful to feed entropy to /dev/random on GNU/Linux. Its generation speed is >= 50kB/sec, and it's more when connected to USB 2.0 Hub. The output is tested NIST STS 2.1.1 and Dieharder 3.31.1. Highlights are: * Replacement of kernel (thread library) Instead of ChibiOS/RT, we now use Chopstx. * Improved performance The output of random numbers got faster than the previous implementation by 30% or so. * Unsupported targets CQ_STARM, STBEE, STBEE Mini, and STM32_PRIMER2 are not supported in this release, but porting should be easy. Here are some links for NeuG, Gnuk and FST-01 (the hardware).
