    "abstract": "A quantum digital signature protocol based on quantum mechanics is proposed\nin this paper. The security of the protocol relies on the existence of quantum\none-way functions by quantum information theorem. This protocol involves a\nso-called arbitrator who validates and authenticates the signed message. In\nthis protocol, we use privacy key algorithm to ensure the security of quantum\ninformation on channel and use quantum public keys to sign message. To\nguarantee the authenticity of the message, a family of quantum stabilizer codes\nare employed. Our protocol presents a novel method to construct ultimately\nsecure digital system in future secure communication.",
