Generating true random numbers using floating ADC input – myth or facts?

This article shows the feasibility of using ADC input of AVR chip as a source of True Random Number Generator (TRNG). I have prepared the testbed and recorded via UART (115200; 8N1) about 50’000’000 of 32bit random numbers. The tests took about 11 hours (including a time I spent to pray to UART for a … Read more
