摘要

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 bit,it is proven that,when both the polarization mode and the path mode contains entangled-states,the DIQKD protocol gets a better secure key rate than common Bell states.
