Simulation of Network Terminal Information Leakage Prevention Method Based on Improved Digital Filtering
Much noise in network terminal information increases the risk of network information leakage.In order to effectively prevent information leakage and improve information security,this paper presented an improved method of preventing information leakage in digital filtering network terminals.Firstly,the network terminal information was taken as the origin,and the Euclidean distance from the signal point to the current point in the quadrant was used as the weight.Secondly,the signal point was weighted and averaged to obtain the value of the coordinate of the network terminal information center.Thirdly,the window was expanded through the urban distance.After that,the window was used as a filter window to weigh all signal points and thus to complete the network terminal information filtering and reduce the impact of noise on information security.Moreover,the optimal value was obtained by the distributed gradi-ent key management strategy,and then it was set as a private key of the network node to form a key pair.Finally,the key pair was used to sign and encrypt all the network terminal information,thus realizing the anti-leakage processing for network terminal information.Experimental results show that the proposed method can effectively ensure the infor-mation security of network terminals while reducing the space occupation and energy consumption.
