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 bit, it is proven that, when both the polarization mode and the path mode contains entangledstates, the DIQKD protocol gets a better secure key rate than common Bell states.}, DOI = {10.32604/cmc.2020.010042} }
