 note = {Random number generators in digital information systems exploit physical entropy sources, such as electronic and photonic noise, to add unpredictability to deterministically generated pseudo-random sequences. However, there is a large gap between the generation rates achieved with existing physical sources and the high data rates of many computation and communication systems, which is a fundamental weakness in these systems. Here we show that good-quality random bit sequences can be generated at very fast bit rates using physical chaos in semiconductor lasers. Streams of bits which pass standard statistical tests for randomness have been generated at rates of up to 1.7 gigabit per second by sampling the fluctuating optical output of two chaotic lasers. This rate is an order of magnitude faster than that of previously reported devices for physical random bit generators with verified randomness., text, application/pdf},
