秘密和可靠的通信提出了一个挑战，涉及用户和对手的双重困境。对手面临的一个挑战是在干扰和窃听之间做出决定。虽然干扰可以非常有效地阻止用户的可靠通信，但由于他/她可以被检测到，因此它对对手也非常有害。另一方面，窃听是相当安全的对手，但是，它有时可能不是那么有效的相比，干扰，如果对手不能及时响应从窃听收集的信息。用户可以发送，从而变得容易受到恶意活动的攻击，或者处于静音模式，从而延迟他/她的传输。然而，通过适当地组合这些模式，用户可以帮助入侵者检测系统检测对手，因为传输可以激发对手进行干扰攻击，并且在干扰机继续干扰时策略性地分配静默模式可以增加检测对手的概率。在本文中，为了深入了解这个问题，提出了两个简单的随机游戏。显式的解决方案，导致一些有趣的特性的表征。特别是，它示出，在某些条件下，在传输协议中纳入一个时隙处理只是与恶意威胁的检测可以提高通信的保密性和可靠性，而无需额外的传输延迟。
Secret and reliable communication presents a challenge involving a double dilemma for a user and an adversary. One challenge for the adversary is to decide between jamming and eavesdropping. While jamming can be quite effective in preventing reliable communication of the user, it can also be quite harmful for the adversary since he/she can be detected. On the other hand, eavesdropping is quite safe for the adversary; however, it sometimes may not be so efficient compared to jamming, if the adversary cannot respond to the information gleaned from eavesdropping in a timely manner. The user can either transmit, thus becoming vulnerable to malicious activity, or be in a silent mode in turn delaying his/her transmission. However, by combining these modes properly the user can assist an intruder detection system in detecting the adversary, since transmission can provoke the adversary into a jamming attack, and a strategically allocated silent mode while the jammer continues jamming can increase the probability of detecting the adversary. In this paper, to get insight into this problem, two simple stochastic games are proposed. Explicit solutions are found that lead to the characterization of some interesting properties. In particular, it is shown that under certain conditions, incorporating in the transmission protocol a time slot dealing just with the detection of malicious threats can improve the secrecy and reliability of the communication without extra transmission delay.
