In this paper, we investigate the physical layer security technique of a cooperative communication network with a source node having multiple transmitting antennas, in which these antennas provide the most optimal antenna to increase security performance to a destination node via a relay node in the presence of an eavesdropper node.

In practice, fading channel coefficients are estimated imperfectly at receivers. In this paper, I propose and analyze a cooperative communication scheme under physical layer security with imperfect CSI. In this scheme, a source node transmits secure data to a destination node D with a help of a relay node against an eavesdropper node without direct links of source-destination and source-eavesdropper.

In this paper, an approach method to improve secrecy cooperation transmissions using combined signals is investigated in which data and jamming signals are combined at a source node based on power allocation strategy. The secrecy system performances are evaluated using asymptotic secrecy outage probabilities of end-to-end achievable secrecy rates over flat and block Rayleigh fading channels.

This paper presents a novel security analytic method to identify and detect an eavesdropper over the physical layer of massive MIMO systems under Rican channel conditions. The numerical analysis results indicate that the proposal can detect attacks and estimate the probability of false alarms when attackers exist.

In this paper, we propose a novel method to estimate and remove the jamming signals from multiple multi-antenna jammers in a two-way relay network with multi-antenna legitimate and relay nodes. We carefully consider the signals in the time slots in order to exploit the repetition of the signals and design the transmitted signals which can work in different cases.

A great number of efficient methods to improve the performance of the networks have been proposed in physicallayer security for wireless communications. So far, the security and privacy in wireless communications is optimized based on a fixed assumption about the trustworthiness or trust degrees (TD) of certain wireless nodes. The nodes are often classified into different types such as eavesdroppers, untrusted relays, and trusted cooperative nodes. Wireless nodes in different networks do not completely trust each other when cooperating or relaying information for each other.

The system’s architecture is based on an original design that constitutes a vNIC, a physical network interface card (pNIC), and a software. The vNIC creates the virtual host, while the relay system manages the software. Thus, pNIC provides an interface between the physical layer and the software layer. Finally, we conduct empirical testing of the proposed system’s viability using real-life Internet-based research. The results show that our proposed system performs effectively and has good operability.

In this study, our purpose is to distribute interfaces in cloud computing environment in a way that they are useful to optimize resource allocation and to reach the main purpose of this research; that is, to reduce energy consumption. By creating an abstract layer on all physical resources, resources can be managed dynamically by the help of virtualization. Selecting an appropriate and efficient algorithm is required for resource allocation due to dynamic resources and various user requests in cloud technology to increase efficiency.
