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 [[Quantum Digital Signature#Properties|transferability]], [[Quantum Digital Signature#Properties|non-repudiation]] and [[Quantum Digital Signature#Properties|unforgeability]]. In contrast, classical digital signatures rely on authentication (taken as an assumption for some QDS protocols) i.e. the message has come from the claimed party; integrity i.e. the message has not been altered (if authentication is confirmed, this property is unforgeability) and non-repudiation (same as QDS). | 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.

A digital signature not just authenticates an electronic document but also ensures that it has not been tampered with and prevents anyone denying a true signature. Note that QDS schemes sign classical messages and not quantum messages. Signing quantum messages is not possible [[Quantum Digital Signature#References|(1), (2)]]. <br/> | ||
