Abstract
Massive Multiple Input Multiple Output (Ma-MIMO) is regarded as promising technology to enhance the system capacity of 5G wireless communication systems. The main idea behind Ma-MIMO is to equip the base station with very large number of antennas for both transmission and reception and is based on breakthroughs in physical layer. Most of the issues related to Ma-MIMO have been researched throughly and addressed, except security issues. The essential premise of physical layer security (PLSec) is to enable secure transmission of messages over wireless network by keeping it secure from attackers ( i.e eavesdroppers and jammers). The goal of this research is to investigate the PLSec issues pertaining to Ma-MIMO and establish secure communication in the presence of attackers where legitimate users have specified quality of service (QoS) requirements in terms of signal to noise plus interference ratio. PLSec analysis problem is formulated as non-cooperative game consisting of legitimate users and attackers (aka players). Game theoretic approach is used analyze the interaction between competing players in the system. We present the game theory based iterative algorithm to adapt transmit power and transmit symbols of the user to enhance the physical layer security by minimizing the impact of attackers. We evaluate the performance anlaysis of PLSec using numerical results obtained from simulation and demonstrate the effectiveness of the proposed algorithm. We also present the existence and uniqueness of the Nash equilibrium of the proposed game.
