分布式网络数据信息泄露检测仿真研究

摘要

This paper proposes a method for detection of information leakage in distributed network.Firstly,we calculated the probability of information leakage according to join operator to obtain probability of information leakage of non-trust node,and built detection model of the information leakage.Then we used dynamic programming to calculate optimal detection position and located Bloom filter.Moreover,the filter was used to provide detection probability when string length of information is the same,and mechanism of the detection was built.Experimental results show that the method has higher detection precision and lays a foundation for ensuring security and stability of the distributed network.%对分布式网络数据信息泄露检测方法的研究,可保障分布式网络的安全稳定性,提升网络的服务质量.对数据信息的泄漏检测,需要利用滤波器给出信息字符串长度相同时的检测概率,组建信息泄露检测机制,完成对数据信息的泄露检测.传统方法先通过构建分布式无线网桥,得到移动终端网络边界的数据包,但忽略了组建信息泄露检测机制,导致检测精度偏低.提出基于动态规划的分布式网络信息泄露检测方法.上述方法先依据join算子计算信息泄露概率,得到非信任节点信息泄露概率,组建网络信息泄露检测模型,使用动态规划来计算最优检测位置,定位Bloom滤波器,利用该滤波器给出信息字符串长度相同时的检测概率,组建分布式网络信息泄露检测机制,利用上述机制完成对分布式网络信息泄露检测.实验结果表明,所提方法检测精度高,为保障分布式网络的安全稳定性奠定基础.
