| 摘 要： | 为了有效判断网络数据包是否存在被攻击的可能性,提出了一种新的基于云模型的检测算法DMCM(Detection Method based on Cloud Model)。该算法首先结合数据包属性的离散度和偏差定义了状态指标,并根据云模型给出了标准差分布的计算流程,以此判断数据包的异常状况。最后,通过OPNET和MATLAB进行仿真实验,深入研究了影响该算法的关键因素,同时 与其它算法之间进行了性能对比,结果表明DMCM具有较好的适应性。

| Abstract: | In order to effectively determine whether network packets were attacked or not,a new detection algorithm DMCM(Detection Method based on Cloud Model) was proposed based on the cloud mode.Firstly,the state indicator of each packet was defined in terms of the discreteness and deviation of the properties of packets.Then,the process of computing the distribution of standard deviation was presented based on the cloud model.The distribution was used to determine the anomaly states of packets.Finally,a comprehensive experiments were conducted to study the performance of the DMCM algorithm through simulation using OPNET and MATLAB.Experimental results show that the proposed algorithm performs better than other algorithms in terms of adaptability. |
