-Digital Signatures (DS) allow for the exchange of single or multiple bit classical messages from sender to multiple recipients, with a guarantee that the signature has come from a genuine sender and the properties of transferability, non-repudiation and unforgeability (see [[Quantum Digital Signature#Properties|Properties]]).
+Digital Signatures (DS) allow for the exchange of single or multiple bit classical messages from sender to multiple recipients, with a guarantee that the signature has come from a genuine sender and the properties of transferability, non-repudiation and unforgeability (see [[Quantum Digital Signature#Properties|Properties]]). These properties ensure that once signed a classical message with a quantum digital signature (QDS) the sender (seller) cannot deny at a later stage having signed the message, a recipient (buyer) cannot fake or alter the QDS and another sender (verifier) can use the above two properties to verify if the sent message is signed by the genuine sender.
