Deterministic key distribution scheme based on the non-locality of unentangled states

Abstract

In this paper we provide a deterministic key distribution scheme based on the non-locality of untangled states in which people can share a predeterministic string as the key. The fundamental Laws of quantum mechanics guarantee that the scheme is unconditionally secure. There are no entangled states or complex quantum operations needed in our scheme. We show that our scheme is easy to carry out in practice. Moreover our scheme is robust against possible noise and attacks. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2611
