Consider the process of exchanging information between the sender and the receiver through various available channels with the presence of eavesdroppers
The researches on the energy and spectral efficiency problem of massive MIMO enabled HetNets, such as  and , mainly focused on the scenario without the existence of eavesdroppers
However, for relay systems with security concerns, the beamforming technique needs to exploit the channel information of both the destination and the eavesdropper
PrivateEye recognises authorised users and lets them in, protects the screen when they are away, and detects and prevents visual eavesdroppers
In previous works, however, relay nodes that transmit the message received from the source or the jamming signals with the aim of confounding eavesdroppers
, were considered to establish a secure link from the source to the destination in a wireless network.
As a result, the communicating parties have no need to test for eavesdroppers
The word eavesdropper
comes from the act of listening in on others from the eavesdrop (a small empty space below the rain gutters) of others' homes.
Comaniciu is making highly ingenious use of typical impediments and failures in communications in order to protect data from unwanted eavesdroppers
,” says Dr.
Indeed, his party harbours suspicions of eavesdroppers
on its meetings, and sometimes adjourns to a city hotel for a confidential debate.
will be able to send a text message to reprogramme handsets so they can transmit discussions.
Gaylin's exploration of this question is the most fascinating aspect of her analysis; she provocatively asks how we as readers might be implicated as eavesdroppers
and how our status as eavesdroppers
affects our interpretation of texts.
The solution will enable users to see who is on the call at any time, control participants on the call, and provide protection against the risk of uninvited eavesdroppers
