Prepare and Measure Quantum Digital Signature: Difference between revisions

== Functionality Description==

Digital Signatures (QDS) allow the exchange of classical messages from sender to multiple recipients, with a guarantee that the signature has come from a genuine sender. Additionally, it comes with the properties of (i) [[transferability]] i.e. messages with DS can be forwarded from one recipient to another such that DS is verifiable to have come from the original sender, (ii) [[non-repudiation]] i.e at any stage after sending the message to one recipient, sender cannot deny having sent the message and corresponding DS, and (iii) [[unforgeability]] i.e. a dishonest recipient cannot alter or fake the sender's DS and forward it to other recipients successfully.<br/>
