- Abstract: In this paper, a secure quantum dialogue protocol via cavity QED is suggested
by using the evolution law of atom in cavity QED. The present protocol employs
both the two-step transmission and the unitary operation encoding. Two security
checks are adopted to ensure its transmission security against the active
attacks from an outside eavesdropper. The present protocol avoids the
information leakage problem by using the entanglement swapping between any two
Bell states via cavity QED together with the shared secret Bell state. Compared
with the previous information leakage resistant quantum dialogue protocol via
cavity QED, the present protocol takes advantage in quantum measurement.

Quantum secure direct communication (QSDC) uses the quantum channel to transmit information reliably and securely.
In order to eliminate the security loopholes resulting from practical detectors, the measurement-device-independent (MDI) QSDC protocol has been proposed.
We propose a single-photon-memory MDI QSDC protocol (SPMQC) for dispensing with high-performance quantum memory.

In this work, we show that both the protocols are not secure against information leakage, and a third party can get half of the secret information without any active attack.
