Physical layer security is applied to evaluate the cooperative efficiency in terms of the data transmission and data security.
By leveraging MOSS 2007 functionality, C-ME offers subscription capabilities, performs user authentication, establishes and manages permissions and privileges, and has data encryption capabilities to ensure secure data transmission as part of its security package.
At the same time, cooperative relays were applied during data transmission for an additional security transmission purpose.
The wireless environment is mainly addressed by the proposed system, which tries to overcome the severe constraints on security, data transmission capability, and user friendliness imposed by such environment.
Concerning security, data transmission is encrypted and complete user separation is applied.
Also, an efficient Web-Services-based data exchange scheme is developed to solve three core problems of data exchange in ECMS: the convenience of data exchange and integration, the security protection of data transmission, and the efficiency of transmitting data, in particular large binary data.
Data security can be enhanced by storage area encryption, remote wiping (during loss or theft), and WiFi security for secure wireless data transmission.
With the development of active distribution networks, data transmission is facing a severe security challenge.
To protect the security of data transmission, a key cryptosystem can ensure the confidentiality, availability, and integrity of data.
The wide area protection and control takes higher requirements on the real-time performance, reliability and security of data transmission.
So, the security of data transmission in these networks is becoming more critical than ever [1, 2].
