Abstract

The invention relates to a method for constructing an execution set based on mimic defense Sketch, comprising the steps of: randomly extracting Sketches from a standby set to form a running set; dividing the Sketches in the running set into row-granularity Sketch and bucket-granularity Sketch according to a preconfigured strategy ; Map the row granularity Sketch to the rows in the execution body data structure through the row mapping function, and record the mapping relationship; use the bucket mapping function to map the bucket granularity Sketch to the bucket in the execution body data structure respectively, and record the mapping relationship ; When inserting a data packet, call the corresponding Sketch insert function of the bucket data structure corresponding to the hash value of the data packet; when querying an abnormal flow, traverse the execution body data structure and call the corresponding query function. The invention can reduce the extra huge space-time overhead caused by the mimic structure while enhancing the robustness of the network measurement.

Description

technical field [0001] The invention relates to the fields of mimic defense and network measurement, in particular to a method for constructing an execution body set based on a mimic defense Sketch. Background technique [0002] With the development of the Internet, the network environment is becoming more and more complex and diverse, network attack methods emerge in endlessly, and the security situation of cyberspace is severe. In order to avoid the huge loss caused by the failure of network defense, it is necessary to discover potential security threats in time. The network measurement technology represented by Sketch monitors the network in real time, counts traffic information, and accurately feeds back the network status, providing network administrators with real-time information of the network, so it has attracted more and more attention. However, the performance of network measurement will be greatly reduced when the equipment carrying the network measurement funct...
