Abstract

The invention relates to an executor set construction method based on mimicry defense Sketch, and the method comprises the steps: randomly extracting Sketch from a standby set, and building an operation set; dividing the Sketch in the operation set into a row granularity Sketch and a bucket granularity Sketch according to a pre-configured strategy; mapping the row granularity Sketch to rows in anexecutive body set data structure through a row mapping function, and recording a mapping relationship; mapping the bucket granularity Sketch to a bucket in an executive body set data structure through a bucket mapping function, and recording a mapping relationship; when a data packet is inserted, calling a Sketch insertion function corresponding to a bucket data structure corresponding to the hash value of the data packet; and when an abnormal flow is queried, traversing the execution body set data structure, and calling a corresponding query function. According to the method, while the measurement robustness of a network is enhanced, extra huge space-time overhead caused by mimicry construction can be reduced.

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...
