Generation of pseudorandom numbers from audio input in smart phone Android

The nowadays the needs of Random Number Generators (RNG) on the Internet of Things (IoT) devices have been increased such as Android smart phone. On Android devices, there are sources of randomness namely, dev/random Linux PRNG (LPNRG). But there are lacking in a way to get the new data source and extract the randomness of data. In addition, the use of LPRNG we can use another alternative, by using the microphone on Android devices. Microphone on Android devices can be used to obtain the audio input. The process of audio input will produce random noise so that it can be used as a source of randomness. The process of the audio input will need some addition process before being used as a source of data. The process of the utilization of audio input as a source of random data will produce a big size of data, so it should be used with maximum. In this research there will be the utilization of maximum data from the audio input. The results of the random data sources from the audio input will be used as the seed of the algorithm Mersenne Twister. To measure randomness from random numbers that have been produced writer use statistical testing suite tool from National Institute of Standards and Technology (NIST).
