Generation of Random Numbers on a Microcontroller Platform
Abstract
Microcontrollers are widely used in everyday applications as a result of their cheap and versatile nature. Recent advances in the fields of Internet of Things and Artificial Intelligence further increased the application areas of microcontrollers. A major problem of microcontroller applications is the generation of random numbers with the limited hardware resources available. Existing methods which use the jitter in different clock sources or incorporate dedicated random number generators either lack operation speed or need addition of expensive hardware components. This paper uses the avalanche breakdown uncertainty in a transistor to generate random numbers on a microcontroller platform. In the context of this study, a hardware platform is designed to generate random numbers and generated data is analyzed through statistical methods. The presented solution is quite fast and cost effective in terms of both design budget and hardware resources.
