The True Random Number Generator (TRNG) is an important module for countless cryptographically secure appliances. TRNG generation technique requires custom made hardware with quantum phenomena, which on the whole are expensive research components. A secure and sound TRNG design is anticipated at this time, which is based on the permutation of sensor feeds and combination of noise patterns from the peripherals of any Android smartphone. The source for this generator is the selected features from the in-built hardware components namely accelerometer, gyroscope, magnetometer, WiFi signal measure, cell tower information, GPS coordinates and battery thermal noise. Additionally, Process ID (PID) of the corresponding Android processes is given as key vector to augment the entropy and also addresses some of the security concern like confidentiality, integrity and availability of the authentic sources. . Hardware-Based Random Number Generator (HRNG) can be achieved by combing the source of the user, their corresponding parameters and the measure of imperfection.
