“…This paper is devoted to the analysis of the (in)security of the ping-pong protocol -an entanglement based QDC scheme [3]. Quasi security is provided only for perfect quantum channels [14] and the scheme becomes insecure when losses [21] and/or communication errors and imperfection of devices are taken into account [22]. Protocol offers capacity of single bit per protocol cycle because the authenticity of the shared EPR pair is verified only by a measurement in a single basis.…”

The existence of an undetectable eavesdropping of dense coded information has been already demonstrated by Pavičić for the quantum direct communication based on the ping-pong paradigm. However, a) the explicit scheme of the circuit is only given and no design rules are provided, b) the existence of losses is implicitly assumed, c) the attack has been formulated against qubit based protocol only and it is not clear whether it can be adapted to higher dimensional systems. These deficiencies are removed in the presented contribution.A new generic eavesdropping scheme built on a firm theoretical background is proposed. In contrast to the previous approach, it does not refer to the properties of the vacuum state, so it is fully consistent with the absence of losses assumption. Moreover, the scheme applies to the communication paradigm based on signal particles of any dimensionality. It is also shown that some well known attacks are special cases of the proposed scheme. * Piotr.Zawadzki@polsl.pl † miszczak@iitis.pl

We propose a quantum secure direct communication protocol utilizing four-qubit cluster state to enhance the efficiency of eavesdropping detection. In the security analysis, by applying the method of the entropy theory, we contrast our scheme to another two strategies, the Ping-pong protocol and the protocol using two particles of Einstein-Podolsky-Rosen pair as detection particles. The comparison results show that if the eavesdropper obtains the same amount of information, the presented quantum protocol strategy will have a larger detection probability than the other two. At last, the security of the proposed protocol is discussed. The analysis results indicate that the protocol in this paper is more secure. Copyright
