“…Other cryptographic applications have been studied, such as secret sharing or the Byzantine chord problem. The more specific exploitation of quantum entanglement has also led to dense coding [17], quantum teleportation [18] and other applications, also recently a new stady of Quantum 2989 password sharing scheme using trusted servers is published [19]. In a previous work, we have presented the quantum key distribution with several intercept and resend attacks [20] and with several cloning attacks [21], and we have investigated the cases of quantum key distribution with several attacks via a depolarizing channel [22] [23] and partially non-orthogonal basis states [24].…”

<p>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.</p>
