Device-independent quantum cryptography (original) (raw)

A quantum cryptographic protocol is device-independent if its security does not rely on trusting that the quantum devices used are truthful.Thus the security analysis of such a protocol needs to consider scenarios of imperfect or even malicious devices. Several important problems have been shown to admit unconditional secure and device-independent protocols. A closely related topic (that is not discussed in this article) is measurement-device independent quantum key distribution.
