Quantum-locked key distribution at nearly the classical capacity rate [PDF]
, 2014 Quantum data locking is a protocol that allows for a small secret key to (un)lock an exponentially larger amount of information, hence yielding the strongest violation of the classical one-time pad encryption in the quantum setting.

Sterically stabilized lock and key colloids: A self-consistent field theory study
, 2011 A self-consistent field theory study of lock and key type interactions between sterically stabilized colloids in polymer solution is performed. Both the key particle and the lock cavity are assumed to have cylindrical shape, and their surfaces are ...

Multi-Photon Quantum Key Distribution Based on Double-Lock Encryption
, 2015 This paper presents a multi-stage, multi-photon quantum key distribution protocol based on the double-lock cryptography. It exploits the asymmetry in the detection strategies between the legitimate users and the eavesdropper. The security analysis of the
