Though the work in [21, 22] establishes the secrecy capacity of the parallel wiretap channel for the most general case, for the parallel multireceiver wiretap channel, obtaining the secrecy capacity region for the most general case seems to be intractable for now.
But they have criticized as too low the bar that prosecutors must meet to obtain a secrecy order from courts.
w J ∥h je scheme can obtain larger secrecy capacity than CB, MRSJ, and SRSJ schemes.
Then, using Theorem 7, we obtain the secrecy capacity region of the channel with two users and subchannels as given in the following theorem which is proved in Appendix.
With rubber, Vaucanson imagined he would be able to create a system of tubes to convey fluid around the body of his android; unfortunately, difficulties in preserving the elasticity of the resin, together with the need for intense secrecy while obtaining sufficient quantities -- only enough to fill a small package had been imported -- made the project unfeasible.
He let in the barbarians, yet his firm has many other stakeholders, including the family and the 600 employees in Oldenburg.Germany's securities watchdog and the state prosecutor are investigating alleged share-price manipulation; meanwhile, Mr Freitag's firm has been accused of "breach of verbal secrecy" in obtaining evidence.
Besides, the two baseline schemes obtain average higher secrecy capacity compared to the other schemes.
In this scenario, the authors have obtained an achievable secrecy-rate region and some outer bounds.
By adopting the proposed algorithm, almost all the MUEs can obtain a non-zero secrecy capacity and the secrecy capacity of the macro-layer is increased by four times.
Finally, one may consider that the only way of dealing with such issue will consist in obtaining empirical evidence on the respective effects of secrecy and publicity and weighing them up[39].
