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 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.},
