Paper Abstract

Quantum key distribution (QKD) can achieve information-theoretic security, which is a provable security against any eavesdropping, given that all the devices the sender and the receiver employ operate exactly as the theory of security requires. Unfortunately, however, it is difficult for practical devices to meet all such requirements, and therefore more works have to be done toward guaranteeing information-theoretic security in practice, i.e., implementation security. In this paper, we review our recent efforts to enhance implementation security. We also have a brief look at a flaw in security proofs and present how to fix it.
