This paper proposes a quantum fair nonrepudiation information exchange protocol based on quantum public keys signature with Quantum trusted third party (QTTP). In this protocol, a message sender Alice can send a message to a receiver Bob, and when this process finishes, both Alice and Bob can acquire the evidence which prevents each other from repudiating, so the protocol insures the fair non-repudiation. The security of the protocol is also discussed and proved. Comparing to the classic fair non-repudiation protocols, this protocol is more secure because of the principles of the quantum mechanism, such as quantum no-cloning theorem.
