Part of the book series: Lecture Notes in Computer Science ((LNCS,volume 13285))

Included in the following conference series:


We address the problem of sharing an expensive hardware-based high-entropy quantum random number generator (QRNG) among multiple users connected to it via the network. We demonstrate how to 1) divide the limited bandwidth of the QRNG device among multiple clients, 2) secure network communication between the QRNG and its users by applying quantum-safe algorithms, and 3) switch existing client-side applications to use randomness received from the remote QRNG without the need to recompile their code.
