Abstract
In aspects of quantum-based security for hardware devices, a computing device includes a processor for application processing in a trusted execution environment, and includes a quantum random number generator to generate quantum random numbers sourced by multiple hardware devices in the computing device. The computing device also includes an embedded secure element that manages connection security of the multiple hardware devices, and is a single root of trust as a secure controller of the quantum random number generator. The computing device also includes a secure switch controlled by the embedded secure element, the secure switch being switchable to connect at least one of the multiple hardware devices to obtain a quantum random number from the quantum random number generator. The secure switch may be a virtualized secure switch implemented in the embedded secure element.
