Abstract

A non-algorithmic physical random bit generator is introduced, using a graphic processing unit (GPU) as a random source. The generator takes randomness from parallel threads executing atomic instructions. The generator in terms of pass rates from the National Institute of Standards and Technology (NIST)'s statistical test suite and bit generation throughput is evaluated. The generator compares favourably with pseudorandom bit generators known to have fine statistical properties. The test bed Nvidia's GPU GTX 680 can generate random bits at the rate of hundreds of megabits per second. The cost-effectiveness of GPUs as random key generators can be increased, as GPUs are now readily available in most desktop computers, and even in smart phones.
