On the Security of Quantum Key Distribution Ping-Pong Protocol

Abstract

Computational based cryptography might not guarantee long term security if computational algorithms, computers, and so on are made remarkable progress. Therefore, quantum cryptography with unconditionally security attracts attention. In this paper, we consider security of a two-way quantum key distribution protocol, so called Ping-Pong protocol. As a result, we introduce not only robustness but also a different information disturbance theorem, which denotes a trade-off relationship between information gain for an eavesdropper and error rate, from the related works for an attack model.

Improving security of the ping-pong protocol

P. Zawadzki

A security layer for the asymptotically secure ping-pong protocol is proposed and analyzed in the paper. The operation of the improvement exploits inevitable errors introduced by the eavesdropping in the control and message modes. Its role is similar to the privacy amplification algorithms known from the quantum key distribution schemes. Messages are processed in blocks which guarantees that an eavesdropper is faced with a computationally infeasible problem as long as the system parameters are within reasonable limits. The introduced additional information preprocessing does not require quantum memory registers and confidential communication is possible without prior key agreement or some shared secret.

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.

The security of Ping-Pong protocol

Jianchuan Tan, An Min Wang

Ping-Pong protocol is a type of quantum key distribution which makes use of two entangled photons in the EPR state. Its security is based on the randomization of the operations that Alice performs on the travel photon (qubit), and on the anti-correlation between the two photons in the EPR state. In this paper, we study the security of this protocol against some known quantum attacks, and present a scheme that may enhance its security to some degree.

Efficiency increasing method for quantum secure direct communication protocols

Sergiy O. Gnatyuk, Тетяна Олександрівна Жмурко, Paweł Fałat

Particularly vulnerable spot for violation of information security is a data network, since it is impossible to guarantee the data protection when transferring them through a public environment (Internet, telephone lines, radio). Therefore, the information transmitted on different networks, particularly in need of security and the main way of providing it, is using the cryptographic methods. However, recent research has shown that classical cryptography gives a cause to look for new prospects and it could be quantum cryptography. Among all possible quantum cryptography technologies, quantum secure direct communication (e.g. Ping-Pong protocol) does not use any cryptographic transformations, so there is no key distribution problem and eavesdropping can be detected during transfer, thereby improving information transmitting reliability. In this paper security amplification method for Ping-Pong protocol was proposed. This method uses generated ternary pseudorandom sequence and transformations in Galois field. Accordingly, this could increase the protocol asymptotical security and accelerate its work at least 3 times.

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.

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.
