A quantum digital signature scheme based on quantum mechanics is proposed in this paper. The security of the protocol relies on the existence of quantum one-way functions by fundamental quantum principles. Our protocol involves a so-called arbitrator who validates and authenticates the signed message. This scheme uses public quantum keys publicized by the signatory to verify the validity of the signature and uses quantum one-time pad to ensure the security of quantum information on channel.
