Abstract
A system implements a QKD-secured logon widget. The system generates a first random quantum key using a first random measurement basis; transmits over a fiber optic network, a first random quantum key to a device, encrypts a logon widget instruction set using the first random quantum key and a first encryption algorithm, resulting in an encrypted message. The system then transmits the encrypted message, and the device receives a second random quantum key from the system, and measures the second random quantum key using a second random measurement basis, where the second random measurement basis is compared to the first random measurement basis, resulting in a comparison basis result. The system uses the comparison basis result to determine a level of anomalies present in the second random quantum key and a shared key, and, based on the level of anomalies, determines whether to render a logon widget at the device.
