Secondly, we study the scenario where each legitimate receiver wishes to receive an independent message for another subclass of parallel multireceiver wiretap channels.
Studying secure communications under this assumption is of interest in general and can be justified since receiver 2 is actually a legitimate receiver which can receive a confidential message in other communication periods.
where SINR and SINR e respectively, denote the received SINR at the legitimate receiver and the most detrimental eavesdropper.
Wyner, in [2], defined the wiretap channel, and showed that secure communication from a transmitter to a "legitimate" receiver is possible when the signal received by the wiretapper (eavesdropper) is degraded with respect to that received by the legitimate receiver.
Table 1 illustrates the average received power levels and SNR for all legitimate receiver (main channel) locations whereas Table 2 presents the calculated values for the Probability of Nonzero Secrecy Capacity.
We further assume the users are homogeneous, i.e., all the users experience the same received power on average at each of the receivers (the legitimate receiver and the eavesdropper).
Average received power values were obtained via the NetStumbler software for both legitimate receiver and eavesdropper.
The inverse operation, by which a legitimate receiver recovers the concealed information from the cipher using the key, is known as decryption.
Marlon Brown (BAL) — Brown seems to be filling the hole in the Ravens' offense left by Anquan Boldin, as Jacoby Jones is the only other legitimate receiver option on this team other than Torrey Smith.
The difference is that the replacement is made according to a rule defined by a secret key known only to the transmitter and legitimate receiver in the expectation that an outsider, ignorant of the key, will not be able to invert the replacement to decrypt the cipher.
A transmitter and a legitimate receiver exchanged information in the presence of a moving eavesdropper.
