Measurement Device Independent Quantum Digital Signatures (MDI-DS) achieves the functionality of QDS by allowing exchange of messages using the procedure studied in Prepare and Send QDS but without trusting one's measurement devices, thus making the protocol device independent. It uses the security proof of MDI-QKD to the QDS scheme for insecure channels. The example protocol involves three parties and is designed for signing one bit and the authors suggest that longer messages can be signed by iterating the same process. All three conditions that define QDS i.e. non-repudiation, transferability and unforgeability are implied by the protocol.
