【摘要】：隨著客戶端主機性能的不斷提升,多種不同的P2P軟件可以在P2P網(wǎng)絡中同時運行。根據(jù)不同的漏洞編制出不同的P2P蠕蟲對于網(wǎng)絡可能造成巨大危害性,本文提出了多種P2P蠕蟲共同傳播的數(shù)學模型,主要包括以下兩個方面:(1)提出了多種沉默型P2P蠕蟲共同傳播的傳播模型。首先,對于沉默型P2P蠕蟲進行了研究,然后,在共存和不共存條件下,對多種沉默型P2P蠕蟲的傳播進行了建模。在共存情況下,討論了多種沉默型P2P蠕蟲的瀑布型模型;在不共存情況下,分別討論了多種沉默型P2P蠕蟲的直線型、直角型和漸進型模型。進而,通過傳播模型分別討論了各種情況下P2P蠕蟲不會泛濫的條件、無病平衡點、地方病平衡點以及達到平衡點時的穩(wěn)定性。最后,通過仿真實驗對模型進行了驗證,討論了模型中的傳播參數(shù),如感染率,下載速率以及敏感度等因素對多種P2P蠕蟲共同傳播的影響。(2)提出了多種被動型P2P蠕蟲共同傳播的傳播模型。首先,根據(jù)多種被動型P2P蠕蟲的傳播情況,將多種P2P蠕蟲共同傳播分為共存和不共存兩種情況。其次,在共存和不共存條件下分別討論了各種情況下多種被動型P2P蠕蟲不會泛濫的條件。最后,通過仿真實驗對于模型進行了驗證,討論了模型中的傳播參數(shù)對多種被動型P2P蠕蟲共同傳播的影響�；趥鞑ツＰ偷姆治霰砻�,感染率、接觸率和敏感度在蠕蟲的傳播過程中起到了關鍵性作用。并且通過實驗數(shù)據(jù)和傳播模型估計了多種P2P蠕蟲共同傳播的傳播速度和危害性;實驗還進一步表明,在蠕蟲的傳播過程中,通過降低感染率和接觸率的值可以有效的抑制蠕蟲的傳播,這為多種P2P蠕蟲傳播的控制策略提供了依據(jù)。
[Abstract]:With the continuous improvement of client host performance, many different P2P software can run simultaneously in P2P network. According to different vulnerabilities, different P2P worms may cause great harm to the network. In this paper, a mathematical model of co-propagation of various P2P worms is proposed. This paper mainly includes the following two aspects: (1) A multi-peer-to-peer worm propagation model is proposed. Firstly, the silent P2P worm is studied, and then, under the condition of coexistence and non-coexistence, the propagation of various silent P2P worms is modeled. In the case of coexistence, the waterfall model of many kinds of silent P2P worms is discussed, and the linear, right angle and progressive models of many kinds of silent P2P worms are discussed respectively in the absence of coexistence. Furthermore, through the propagation model, we discuss the conditions of P2P worm not overflowing, disease-free equilibrium, endemic equilibrium and stability when the P2P worm reaches the equilibrium point. Finally, the model is verified by simulation experiments, and the transmission parameters, such as infection rate, are discussed. The influence of download rate and sensitivity on the co-propagation of various P2P worms. (2) the co-propagation model of various passive P2P worms is proposed. Firstly, according to the spread of various passive P2P worms, the co-propagation of various P2P worms is divided into coexistence and non-coexistence. Secondly, under the conditions of coexistence and non-coexistence, the conditions of passive P2P worms are discussed. Finally, the model is verified by simulation experiments, and the influence of propagation parameters in the model on the co-propagation of various passive P2P worms is discussed. Analysis based on propagation model shows that infection rate, contact rate and sensitivity play a key role in the transmission of worms. And through the experimental data and propagation model to estimate the spread speed and harm of various P2P worms, the experiment further shows that, in the process of worm propagation, By reducing the value of infection rate and contact rate, the worm propagation can be effectively inhibited, which provides a basis for various P2P worm propagation control strategies.
