초록
We propose a quantum digital signature in a network consisting of one signer, multiple verifiers, and a trusted center (TC). The protocol guarantees that messages and signed messages are not counterfeited, and it authenticates the source of the messages. In addition, a signer (or a verifier) cannot, at a later time, deny having signed (received) the message. Theoretically, our quantum digital signature guarantees the security through quantum mechanics.
