Abstract
A method may include: sharing, by a client computer program and a server computer program, a set of identification keys, each identification key associated with a key label, and an authentication key; selecting, by the client computer program and the server computer program, one of the key labels; preparing, by the client computer program, quantum systems using a basis, randomly chosen bit values, and intensities; sending, by the client computer program, the quantum systems to the server computer program over a quantum communication channel, wherein the server computer program may be configured to measure the quantum systems using the basis and to announce quantum systems with photon detection; and generating, by the client computer program, a client tag using a shared keyed hash function executed on the authentication key and chosen bit values from the quantum systems with photon detection, and forwarding the client tag to the server computer program.
