【摘要】：隨著科技的發(fā)展,無線通信已經(jīng)成為一種有效的現(xiàn)代通訊技術(shù),并被廣泛采用。但是由于無線通信的廣播天性,保密和安全性能在無線通訊的技術(shù)發(fā)展中起著越來越重要的作用。在存在竊聽者的無線通信中,節(jié)點之間的協(xié)作可以有效地提升物理層安全。然而,當(dāng)中繼節(jié)點為不可信節(jié)點時,這些節(jié)點可能采取自私行為甚至惡意行為,無線通信的安全性能將因此受到嚴(yán)重影響。一種有效的解決方式,提前預(yù)測不可信節(jié)點行為,找到合適的防御策略。在本文中,作者采用多節(jié)點模型,該模型包含多個不可信中繼,一個竊聽者,源節(jié)點和目的節(jié)點。該模型采用固定放大轉(zhuǎn)發(fā)中繼協(xié)議(AF),并將中繼權(quán)重?和惡意指數(shù)β作為重要參數(shù)。本文運用數(shù)學(xué)中非零和博弈的方法,建立了不可信節(jié)點群行為和監(jiān)測系統(tǒng)策略之間的聯(lián)系。其中,安全容量用以表示在不可信節(jié)點群采取不同行為后的收益。最后,論文提出一種算法,用以預(yù)測不可信節(jié)點群的行為,以及對應(yīng)的系統(tǒng)最優(yōu)監(jiān)測策略。
[Abstract]:With the development of science and technology, wireless communication has become an effective modern communication technology and widely used. However, due to the nature of wireless communication, security and security play a more and more important role in the development of wireless communication technology. In wireless communication with eavesdroppers, the cooperation between nodes can effectively improve physical layer security. However, when the relay nodes are untrusted nodes, these nodes may take selfish behavior or even malicious behavior, so the security performance of wireless communication will be seriously affected. An effective solution to predict the behavior of untrusted nodes in advance and find appropriate defense strategies. In this paper, the author uses a multi-node model, which includes multiple untrusted relays, an eavesdropper, a source node and a destination node. The model adopts the fixed amplification relay protocol (AF),) and weights the relay. And malicious index 尾 as an important parameter. In this paper, the relationship between the behavior of untrusted node group and the strategy of monitoring system is established by using mathematical non-zero sum game method. The security capacity is used to represent the benefit of different behaviors of the untrusted node group. Finally, an algorithm is proposed to predict the behavior of untrusted nodes and the corresponding optimal monitoring strategy.
