Problems solved by technology

However, in actual positioning, the area where the target IP is located is also unknown in many cases, and when the correlation between the delay and distance between nodes is weak, the method of calculating the distance constraint for the target IP based on the delay is not always possible. Get a valid targeting area

Embodiment Construction

[0021] For a certain detection source and destination area, the path characteristics refer to a group of intermediate routers from the detection source to the target IP located in the destination area. After a large number of path detection experiments, it is found that the path from the same detection source to the same destination area The characteristics are relatively similar, but the path characteristics of the same detection source to different destination areas are quite different. Therefore, the regional location method of target IP based on the path characteristics of different destination areas is reliable and accurate.

[0022] Such as figure 1 As shown, a kind of regional level target IP positioning method based on path feature of the present invention, comprises the following steps:

[0023] A. Select multiple areas where the target IP may be located as the target area, and then go to step B. Among them, the Whois database can be used to query the location inform...

Abstract

The invention discloses a regional target IP locating method based on path features. The method comprises the following steps: A, selecting a plurality of regions in which a target IP is possibly located as destination regions; B, selecting a plurality of landmark IPs located in each of the destination regions, and acquiring communication paths from a detection source to the plurality of landmark IPs in each of the destination regions; C, calculating candidate features of each of the destination regions according to all intermediate router interface IP addresses on each of the communication paths and the numbers of hops between intermediate routers and the detection source; D, calculating the path features of each of the destination regions according to the obtained candidate features; E, acquiring a communication path from the detection source to the target IP, and calculating a path feature of the target IP; and F, calculating similarity between the path feature of the target IP and the path features of each of the destination regions, and selecting a locating region of the target IP. Through adoption of the method, high error rate due to IP locating through time delay of dynamic change between nodes is avoided, and the reliability of target IP regional locating is enhanced.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for locating an area-level target IP based on path characteristics. Background technique [0002] IP positioning refers to determining the location of the network entity corresponding to the IP address in geographic space. As location-based services (LBS for short) become more and more popular, the application of IP positioning technology is also increasing, such as embedding advertisements targeting the region where visitors are located in web pages; adjusting the display language of web pages according to geographical location; analyzing web pages Access logs to extract market data; define the geographical scope of electronic taxation; discover illegal activities such as network fraud and attacks, and conduct network forensics, etc. It can be seen that IP positioning technology has very broad application prospects in the commercial market, network securit...
