Security enhancement of D2D communication based on handshaking mechanism

Device-to-device (D2D) communication is such a paradigm that appears to be a sustainable alleviation for the existing cellular network as the existing network struggling to accommodate the excessive amount of data demand for the cellular users due to the scarcity of the wireless resources. Security threats are the critical impediment to achieve the purpose of the D2D communication as attackers may easily intercept the wireless communication link due to the vulnerable attribute of the wireless communication channel and its broadcasting nature which degrades the performance of the D2D communication. The highest possible security steps need to take into account to upgrade the performance of the D2D communication. In D2D communication, the network layer is the vital layer as data routing and transmission are performed throughout this layer and attackers constantly attempts to affect the transmitted data through this layer. In this paper, we propose three ways secure handshaking mechanism to emphasize the security of the D2D communication by ensuring the secure transmission channel between two users, authenticating the users and encrypting the transmitted data. Thus, the propose handshaking mechanism minimizes security threats and maximizes the performance of D2D communication.
