摘要

An arbitrated quantum signature (AQS) scheme is demonstrated via the improved quantum chaotic encryption algorithm with the quantum one-time pad based on chaotic operation string. In this scheme, the signatory signs the message and the receiver verifies the signature's validity with the aid of the arbitrator who plays a crucial role when a dispute arises. Analysis shows that the signature can neither be forged nor disavowed by the malicious attacker.
