摘要：
The research on enhancement of network anti-attack performance can effectively improve the security of multilayer network.The traditional method ignores the internal data of link encryption,which leads to unideal effect.This article presents a method for enhancing anti-attack performance of multilayer network based on bloom filter.Firstly,the linear arithmetic encoding design is used for data on link layer,and residual characters in link one by one are coded.Then the final encoding interval is obtained.Moreover,any number of binarization processing is selected to get the compressed sequence of link.By using bloom filter to hide the address of data link,the link encryption for intemal data is carried out.Thus,the enhancement of multilayer anti-attack performance is finished.Simulation results show that the proposed method can effectively improve the anti-attack performance of multilayer network and make the network more secure.%对网络抗攻击性能强化问题进行研究,能够有效提高多层网络安全性.对多层网络抗攻击性能的强化,需要获取数据链路压缩序列,对内部数据进行链路加密,完成网络抗攻击性能的强化.传统方法先对数据链路进行安全协议配置,设置链路特征函数,但忽略了链路加密内部数据,导致强化效果不理想.提出基于布隆过滤器的多层网络抗攻击性能强化方法,先对链路层数据进行线性算术编码设计,将链路中剩余字符逐个编码,得到最终编码区间,选择任意数进行二值化处理,得到链路压缩序列,借助布隆过滤器隐藏数据链路地址,对内部数据进行链路加密,完成多层网络抗攻击性能的强化.仿真研究证明,所提方法能够有效提高多层网络的抗攻击性能,使网络更安全.
