In the following, we denote the channel capacity of each user (either CU or D2D) by [C.sub.user], and the channel capacity of the eavesdropper by [C.sub.eaves].

In quantum communication, the eavesdropper is sure to be detected owing to quantum no-cloning theory.
More than 170 apps vulnerable to the Eavesdropper are still live in app stores including the Google Play Store and Apple's App Store.
An eavesdropper who knows the originator Ti of each bit can decode only the bits that was communicated publicly.
This scheme is aimed at the network model with a mobile eavesdropper, whose CSI is unknown to the legitimate users.
The experiment assumes that the eavesdropper has infinite computing power but limited quantum memory and so can't collect lots of information over time about the messages and put it all together to crack the code.
Among the aforementioned works in the area of beamforming for PLS purposes, [7] studied beamforming schemes for decode-and-forward (DF), amplify-and-forward (AF), and cooperative jamming where all available relays were adopted, either to retransmit the source signal or to send an artificial noise to confound the eavesdropper. Null-space beamforming was proposed in [8] to hide the information signal in the null-space of the relay-eavesdropper channel.
If the channel conditions between the legitimate transceiver and the destination are worse than those between the source and the eavesdropper, then using multiple antenna systems and node cooperation is preferable [5]-[8].

Legitimate users must transmit the qubit with the secret message in the public channel under any local operation and classical communication (LOCC) in order to obtain the secret message from the other party; however, an eavesdropper could steal the qubits or attack the protocol without being discovered.
