Design and Implementation of Random Number Generator System Based on Android Smartphone Sensor
摘要
An android smartphone has various types of sensors in its device. All of these sensors produce data based on environmental condition that exists around the device. These data have the potential to be used as the random number because of its non-deterministic component. To realize it, some steps need to be carried out, such as knowing the characteristic of the sensor, estimating the entropy value possessed by the sensor data, and so on. As a proof-of-concept, this research is conducted to design and implement the entropy source and pseudorandom number generator based on the android sensor. The research result shows that by using accelerometer data with XOR result as the input of entropy source and HMAC DRBG as the pseudorandom number generator, so the high quality of random number based on the android sensor can be obtained.
