This algorithm reduces the complexity of optimal joint resource allocation and can ensure all the users' secrecy rate effectively.
On the other hand, the auction can also ensure the competitive fairness among all the bidders, and thus, all the users' secrecy rate can be guaranteed.
The distributed auction can not only reduce the complexity of solving the power allocation problem but also can ensure all the users' secrecy rate.
One of the basic methods of improving the legitimate users' secrecy capacity in physical layer security is interfering the eavesdropper through the artificial noise, which is called friendly jamming or cooperative jamming.
Assuming that the user's secrecy rate requirement is ( {R}_s^0 ), the user link secrecy rate demand will be satisfied when ( {R}_sge {R}_s^0 ) is satisfied.
This paper examines the privacy awareness and importance of user's secrecy preserving in the current cloud computing era.
Using our proposed scheme enables service providers to provide time-bounded multimedia content or services and guarantees user privacy, data integrity, confidentiality, and non-repudiation, as well as forward secrecy and backward secrecy of transferred digital rights with low computation costs.
If we consider the parallel degraded multireceiver wiretap channel with more than two subchannels and an arbitrary number of users, the secrecy capacity region for the scenario where each user receives a common message in addition to an independent message does not seem to be characterizable.
As mentioned previously, the suboptimal scheme sorts the SIC order by users' channel gains (equivalently, main capacities) from the lowest to the highest, while the optimal scheme schedules via users' achievable secrecy rates.
Banks are not legally obliged to tell their customers why they have closed their accounts and World-Check binds its users to secrecy about use of the database.
