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
This project is very similar to ATtiny13 – randomly flashing LED with PRNG based on LFSR. However, this time I used BBS (Blum-Blum-Shumb) algorithm as PRNG (Pseudo Random Number Generator) to generate 16-bit (pseudo) random numbers. The less significant bit of randomly generated number is a major factor in decision to on/off the LED. The code is on Github, click here Parts Required … Read more
Many applications require random data to feed their algorithms. One would say that it’s quite easy when we can use a function from an existing cryptographic library. However, even if we can use such function like for example rand() from stdlib, it can quickly turn out, that this feature consume more then a half of … Read more
This Project simply flashes the LED in random manner. It uses PRNG (Pseudo Random Number Generator) based on LFSR (Linear Feedback Shift Register) to generate 16-bit (pseudo) random numbers. The less significant bit of randomly generated number is a major factor in decision to on/off the LED. The code is on Github, click here See … Read more
