In this work, a qualified audio random number generator that could be used in voice communication is presented. The audio random number generator needs only a microphone or a common equipment such as cellular phone or laptop, to generate qualified random number sequences. When applying NIST SP 800–22rev1a (published in April, 2010) 15 statistical tests on the audio random number generator, around...
Random number plays a central role in statistics sampling, probability, gambling, cryptography, and everything with unpredictability. In general, the random real numbers are generated from a sequence of random binary numbers. We will propose a pseudo random number generator that generates a random-like real number sequence first and then extracts a specific bit of every real number as the binary random...
Random number generators play a very import role in modern cryptography, especially in personal information security. For example, to generate random number from white noise of webcam is a new approach for personal device. Through our algorithms, 91% IPcam generating sequences pass at least four statistical tests, 87% pass all five ones has been approved. Compared with webcam and video respectively,...
