* There exists authenticated classical channels between Sender and Receiver and Sender and Verifier.
* There exists authenticated classical channels between Sender and Receiver and Sender and Verifier.
* Receiver and Verifier share a MDI-QKD link, used to transmit classical messages in full secrecy
* Receiver and Verifier share a [[MDI-QKD link]], used to transmit classical messages in full secrecy

Quantum Digital Signature protocols can be separated into two stages: the distribution stage, where quantum public keys are sent to all recipients, and the messaging stage, where classical messages are sent and verified. Here, we take the case of three parties, one sender (referred to as seller) and two receivers (buyer and verifier) sharing a one bit message.\newline
