The multi-input multi-output (MIMO) transmission against a smart attacker has recently been formulated as a non-collaborative game, in which the reinforcement learning-based transmitter is devised to suppress the attack motivation of the malicious attacker for more secure transmission. Basically, large enough transmission power is needed to obtain the Nash equilibrium in favour of the MIMO transmitter. When energy efficiency is required, a secure MIMO transmission design with reasonable energy efficiency will become highly desirable. This study focuses on how to make the MIMO transmitter not only resist malicious attacker but also realise reasonable energy efficiency. To this end, a new game between the MIMO transmitter and the malicious attacker is formulated to take into account the energy efficiency of the MIMO transmitter. Since the energy efficiency requirement tends to reduce the transmission power by the MIMO transmitter, which may degrade the realised security performance in an adverse environment, the probabilistic transmission strategy was employed to further enhance the secure transmission. The analysis results unveil that the proposed energy-efficient secure MIMO transmission design can not only ensure reasonable security performance but also noticeably improve energy efficiency performance.

智能攻击者在场的节能高效MIMO传输

最近，针对智能攻击者的多输入多输出（MIMO）传输已被公式化为非协作游戏，其中设计了基于强化学习的发送器以抑制恶意攻击者的攻击动机，从而实现更安全的传输。基本上，需要足够大的传输功率来获得Nash平衡，从而有利于MIMO发射机。当需要提高能效时，将非常需要具有合理能效的安全MIMO传输设计。这项研究的重点是如何使MIMO发射机不仅能够抵御恶意攻击者，还可以实现合理的能源效率。为此，制定了MIMO发射器和恶意攻击者之间的新游戏，以考虑到MIMO发射器的能效。由于能效要求往往会降低MIMO发射机的发射功率，这可能会降低在不利环境中实现的安全性能，因此采用了概率传输策略来进一步增强安全传输。分析结果表明，提出的节能安全的MIMO传输设计不仅可以确保合理的安全性能，而且可以显着提高能效性能。
