Abstract
We present a device-independent quantum secret sharing scheme in arbitrary even dimension. We propose a -dimensional -partite linear game, utilizing a generic multipartite higher-dimensional Bell inequality, a generalization of Mermin's inequality in a higher dimension. The probability of winning this linear game defines the device-independence test in the proposed scheme. The security is proved under a causal independence assumption on measurement devices and it is based on the polygamy property of entanglement. By defining correctness and completeness for a quantum secret sharing scheme, we also show that the proposed scheme is correct and complete.
