Abstract

The new quantum protocol of secret sharing between two subjects, which is based on the ping-pong protocol of quantum secure direct communication, is proposed. This protocol is based on scheme of transmission of the qubits by blocks, which is well known from publications. However, in contrast to this scheme in the proposed protocol the data transmission in a random way alternates with channel check on eavesdropping. Thereby the need for periodic storage of considerable number of qubits disappears. It will let to implement the procedure of secret sharing with assisting state-of-the-art technology of quantum information science. The proposed secret sharing protocol, which also uses the earlier developed by co-author the method of enhancement of the ping-pong protocols security, provides the high level of security to the outer malefactor’s eavesdropping attack. It is the advantage of this protocol over the appropriate classical (non-quantum) schemes.

A new quantum secret sharing protocol based on the ping-pong protocol of quantum secure direct communication is proposed. The pairs of entangled qutrits are used in protocol, which allows an increase in the information capacity compared with protocols based on entangled qubits. The detection of channel eavesdropping used in the protocol is being implemented in random moments of time, thereby it is possible do not use the significant amount of quantum memory. The security of the proposed protocol to attacks is considered. A method for additional amplification of the security to an eavesdropping attack in communication channels for the developed protocol is proposed.

A “Ping-pong” Protocol with Authentication

Chen Zuning, Zheng Qin

The quantum secure direct communication is a new-style quantum communication scheme. It arouses much interest recently. The ping-pong protocol proposed by Bostroem and Felbinger is one of relatively mature quantum secure direct communication protocols, which is asymptotically secure under Eve's eavesdropping attack. But it ignores the message authentication. Being aimed at this problem, we propose a novel ping-pong protocol with authentication. The former has two operation modes, or the message mode and the control mode, which are used to send message and detect Eve's attack, respectively. But it just detects Eve's eavesdropping attack and does not authenticate the sent message in the control mode. The latter has also the above two operation modes, which employs a braid-based key agreement protocol for both the parties participating in communication to share a secret, whose size and magnitude are undecided in advance. Using the shared secret, it not only detects Eve's eavesdropping attack, but also effectively performs the message authentication in the control mode. It is also asymptotically secure under Eve's eavesdropping attack. The security of the proposed protocol is based on the no-cloning theorem, the correlations of quantum entanglement and the fact that the p-th root finding problem on braid groups is intractable even on quantum computers, as well as classical computers. In addition different from the original ping-pong protocol, the communication was initiated by the sender Alice instead of by the receiver Bob. This corresponds to the way of common communications. The present protocol not only can resist the attacks known recently, but should be experimentally feasible using today's technology.

Experimental realisation of a deterministic secure quantum communication protocol based on entangled photons

Nino Walenta, Martin R. Ostermeyer

Quantum cryptography protocols using entangled qubit pairs can increase the rate and security of information exchange through a quantum channel. Usually those protocols are non-deterministic, i.e. a classical bit is encoded in a quantum state, but the actual bit value cannot be determined. Therefore they request the transmission of additional information through a public channel. By contrast, the ping-pong coding scheme based on entangled photons allows for deterministic and direct key distribution. No qubit has to be discarded and information can be decoded without the need for a subsequent transmission of additional information. Communication through a public channel nevertheless is necessary to ensure asymptotical security against arbitrary eavesdropping attacks.

Eavesdropping on the “Ping-Pong” Quantum Communication Protocol

Antoni Wójcik

Security of the "ping-pong" quantum communication protocol recently proposed by Boström and Felbinger [Phys. Rev. Lett. 89, 187902 (2002)]] is analyzed in the case of considerable quantum channel losses. The eavesdropping scheme is presented, which reveals that the ping-pong protocol is not secure for transmission efficiencies lower than 60%. Our scheme induces 50% losses, which, however, can be hidden in the channel losses if one replaces the original lossy channel with a less lossy one. Finally, a possible improvement of the ping-pong protocol security is proposed.

Insecurity of "Ping-Pong" Quantum Communication Protocol

Ying Guo

Ping-Pong quantum communication protocol may be employed to transmit deterministically information, so it has instrigued mang researchers. However, there are drawbacks on the security due to the symmetry of the employed two-way quantum channel. In this paper we propose a new attack strategy to eavesdrop the initially transmitted information based on the techniques of quantum error correction code (QECC). In addition, an attack strategy of Ping-Pong scheme based either entanglement state or nonorthogonal state is proofed and demonstrated, respectively. Furthermore, information obtained by Eve and the possible probability detected by the legitimate communicators are analyzed by employing information theorems. Detail proofs and analysis illustrate all previous Ping-Pong quantum communication schemes are insecure, i.e., the eavesdropper may obtain all available information without being detected.

An efficient modification to the ping-pong protocol to enhance the security

Hargeet Kaur, Kavit Shah

Ping-Pong protocol is a Quantum Secure Direct Communication protocol that fails to transfer a secure key or secret message optimally in a lossy or noisy channel. The reason is an eavesdropper who possibly hides in the light of these channel losses and gains information about the secure key bits or secret messages. We propose an efficient modification to the control mode of the original Ping-Pong protocol leading to the detection of an eavesdropper with a much higher probability which may not allow her to hide in the light of lossy channels. Assuming that Eve knows and makes a fixed number of right guesses about the modification in the protocol, an optimum ratio of modification can be evaluated. In addition, it is shown that incorporation of the proposed modification in the protocol doubles the eavesdropper’s detection probability for certain eavesdropping operations.
