Quantum enigma machine: Experimentally demonstrating quantum data locking by Lum, Daniel J., Howell, John C., Allman, M. S., Gerrits, Thomas, Verma, Varun B., Nam, Sae Woo, Lupo, Cosmo, Lloyd, Seth

“…We present one of the first feasible experimental demonstrations of quantum data locking for direct communication and propose a scheme for a quantum enigma machine that encrypts 6 bits per photon (containing messages, new encryption keys, and forward error correction bits) with less than 6 bits per photon of encryption key while remaining information-theoretically secure.…”

Robust and Secure Medical Image Watermarking for Edge-Enabled e-Healthcare by Priyanka Singh, K. Jyothsna Devi, Hiren Kumar Thakkar, Muhammad Bilal, Anand Nayyar, Daehan Kwak

“…The Electronic Patient Record (EPR) is encrypted using a pseudorandom key, which is generated adaptively from the host medical image and the Enigma machine. The encrypted EPR is then embedded in the medical image using NMI. …”
