Random number generation based on MCU sources for IoT application

Wireless sensor communication is managing critical applications that require serious security and privacy concerns to decrease hacking attacks. As a solution, most cryptographic algorithms include secure encoding and decoding which are based on random number generator (RNG), This paper suggests an efficient solution for the generation of low cost and low power random number for Internet of Things' Application based on analog and digital sources of the Microcontroller Unit (MCU) with external sensing resources. The design detail and the validation of the quality of the solution outputs, were identified based on a couple of test suites standardized by the U.S. National Institute of Standards and Technology, both achieved in the ideal case and assuming implementation.
