Abstract The secure key rate of quantum key distribution (QKD) is greatly reduced
because of the untrusted devices. In this paper, to raise the secure key rate of QKD, a
device-independent quantum key distribution (DIQKD) protocol is proposed based on
hyper-entangled states and Bell inequalities. The security of the protocol is analyzed
against the individual attack by an adversary only limited by the no-signaling condition.
Based on the formalization of Clauser-Horne Shimony-Holt (CHSH) violation
measurement on local correlation, the probability of a secure secret bit is obtained, which
is produced by a pair of hyper-entangled particles. By analyzing the secure secret… More >
