Downsizing QRNG Chips for IoT Devices (E20a)
With the development of IoT, millions and soon billions of autonomous devices are getting connected. One crucial step, which is necessary for the security of these devices, is to ensure that they can generate good cryptographic keys. Since they operate in a variety of environments, including possibly entropy-starved ones, an internal entropy source, independent of the surroundings, is required. This source has to be small, rugged, power-efficient and low-cost. A quantum random number generator chip, now used for example in mobile phones checks all the boxes. We will outline the principle and present the possible applications of this chip.
