*'''Messaging:''' Sender sends her message bit with the associated private keys to the Buyer. Buyer performs the map on the private key (quantum one way function takes the sent private key as input) and then compares the output thus generated with the public key received in the distribution stage. If the number of unmatched bits are below rejection threshold, the message is declared valid, else invalid. If the number of unmatched bits is below acceptance threshold, it is declared transferable, else not transferable. | *'''Messaging:''' Sender sends her message bit with the associated private keys to the Buyer.
