Information Leakage Prevention in Quantum Dialogue Using the Measurement Correlation after Entanglement Swapping and Decreasing the Transmission Efficiency
In order to solve the security threat of information leakage in quantum dialogue protocols, a controlled quantum dialogue protocol without information leakage was proposed, where the controller Alice controlled the bidirectional communication between two communication parties, Bob and Charlie. The problem of information leakage was avoided by making full use of the measurement correlation property after entanglement swapping between two maximally entangled GHZ states and decreasing the transmission efficiency. Moreover, the Bellbasis measurement rather than the GHZbasis measurement was needed. Security analysis shows that the active attacks from an outside eavesdropper can be detected, such as the interceptresend attack, the measurementresend attack and the entanglementandmeasurement attack.
