If a person sends some information over an insecure channel (a dishonest/malicious party has access to the channel), what is the guarantee that the receiver on the other end will receive the same information as sent and not something which is modified or replaced by the dishonest party? Authentication of quantum channels/quantum states/quantum messages provides this guarantee to the users of the channel. Note that, it is different from the functionality of [[Quantum Digital Signature|digital signatures]] which comes with additional properties (non-repudiation, unforgeability and transferability). Also, authenticating quantum states is possible but signing quantum states is impossible, a result first stated in [[Authentication of Quantum Messages#References|(1)]] | If a person sends some information over an insecure channel (a dishonest/malicious party has access to the channel), what is the guarantee that the receiver on the other end will receive the same information as sent and not something which is modified or replaced by the dishonest party? Authentication of quantum channels/quantum states/quantum messages provides this guarantee to the users of the channel. Note that, it is different from the functionality of [[Quantum Digital Signature|digital signatures]], a multi-party protocol, which comes with additional properties (non-repudiation, unforgeability and transferability).
