An Arbitrated Quantum Signature Scheme Based on Chaotic Quantum Encryption Algorithm
Ying Guo, Jun Xie, Jun Li, Moon Ho Lee · Journal of Modern Physics · 2013
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.
