True Random Number Generator for a True Hacker

True Random Number Generator for a True Hacker

Two PIC18F2525s with 8-bit one-way parallel communication, supported by simple handshaking. Slave MCU generates 16 random bytes, each of them based on 248 bytes of uninitialized internal Data RAM. Master MCU (shown in the middle above) receives those bytes and sends them to a desktop PC through the RS232 port. After receiving a 16-byte string, master CPU uses the PNP transistor to power off the slave MCU for 200 ms, which will supposedly create new random contents of RAM (according to my experiments, the “Zombie Ram” effect in 8-bit PIC MCUs takes place if the unit was switched off for less than 85 ms). Then the whole process is repeated 625,000 times, for a total of 10 MB of binary data, needed for randomness tests. It takes about 50 hours (the average rate is 56 bytes/sec). For the second test the same master MCU is used, but this time the slave is a 16-bit MCU 24EP512GP...
