Abstract

A new eavesdropping strategy for BB84 quantum key distribution protocol is proposed. This scheme is a new kind of intercept/resend strategy based on Breidbart basis. Under this scheme, eavesdropper can not only exactly obtain the exchanged information between legitimate users but also decrease the probability of being detected.

On the Breidbart eavesdropping problem of the extended BB84 QKD protocol

Li Yang, La Wu, Liu Sh

We discuss the Breidbart eavesdropping scheme of the extended BB84 quantum key distribution protocol. Calculation of the effective average Alice/Eve mutual information after performing a standard error-correction under various intercept/resend strategies shows that the Breidbart eavesdropping/Breidbart resend strategy (B/B strategy) is the most effective one. Sine Alice and Bob can test openly whether there is the B/B eavesdropping by making use of the rejected data, we suggest an amendment of the BB84 protocol to reduce the requirements of the privacy amplification algorithm and hence reduce the quantum key loss. Finally, we present a quantum key regeneration method for error-correction which may be more secure than the standard error-correction process.

A Novel Basis Splitting Eavesdropping Scheme in Quantum Cryptography Based on the BB84 Protocol

Nan Zhao, Changhua Zhu, Dongxiao Quan

We propose a novel strategy named basis-splitting scheme to split the intercepted quanta into several portions based on different bases, for eavesdropping in the process of quantum cryptography. Compared with intercept-resend strategy, our simulation results of the basis-splitting scheme under the non-ideal condition show a greater performance, especially with the increase of the length of shifted bits. Consequently our scheme can aid eavesdropper to gather much more useful information.

The attack strategy for a quantum key distribution protocol based on Bell’s theorem

Chan Myae Hein, T. F. Kamalov

Abstract A new eavesdropping strategy is proposed for the Quantum Key Distribution (QKD) protocol. This scheme represents a new kind of intercept/resend strategy based on Bell’s theorem. Quantum key distribution (QKD) provides the foremost reliable form of secure key exchange, using only the input-output statistics of the devices to realize information-theoretic security. In this paper, we present an improved QKD protocol that can simultaneously distribute the quantum secret key. We are already using the QKD protocol with simulated results matched completely with the theoretical concepts.

BB84 with Both Several Cloning and Intercept-resend Attacks

Mustapha Dehmani, El Mehdi Salmani, Hamid Ez-zahraouy A +1 more

The goal of the protocol QKD BB84 is to allow a transmitter and a receiver which uses a quantum channel to exchange their keys and to detect the presence of eavesdropping attacks. In the present research, we investigate the effect of several eavesdroppers with both intercept-resend and cloning attacks. We will propose the different possible cases of the positioning of the eavesdroppers and their strategies of attacks; also we will calculate the mutual information for each case. The explicit expressions of the mutual information and quantum error clearly show that the security of the exchanged information depends on the numbers of the eavesdroppers and their attacks parameters on the quantum channel.
