It’s a field that need not be expensive or difficult to work in, as [Henk Mulder] shows us with his 4-bit analogue random number generator. One of the simplest circuits for generating random ...

Random generator: The digital circuits at the center of this electron micrograph image can emit a stream of random numbers at high speed. Such circuits could be integrated into future processors.

True random numbers from a handful of gates Even RFID tags could get ‘true’ random number generators following work at the Queen’s University Belfast. Secure communication can require a ...
