Embodiment Construction

[0037]The present invention will be further elaborated below in conjunction with specific examples.

[0038] like figure 1 As shown, the steps of the tracking method include marking the data packets with a certain probability, extracting the data packet information through the base station, reconstructing the attack path, confirming the attack and taking measures.

[0039] The tag information (first, top, tail, start, end, distance) of the packet contains six tag fields. The six label domains are divided into two layers. The first layer consists of (first, top, tail), which is mainly used to reconstruct the backbone part of the path. The second layer consists of (start, end, distance), which is used to reconstruct the local path from the common node start to the cluster head node top in the cluster.

[0040] The meanings of these six marked fields: the first field indicates the ID of the first cluster head node that the attack data packet passes through, and the first fiel...

Abstract

The invention discloses a method of tracking DDoS (distributed denial of service) attack in the wireless sensor network. According to the method, data packets are marked, and source tracking is performed by utilizing the marked data packets, so as to identify malicious attack nodes. The marking method comprises the following steps: setting marking information (first, top, tail, start, end, distance) of six marking domains in the data packets, then marking cluster head node data packets and common node data packets, and discovering attack paths and proceeding accordingly through path reconstruction. The method has excellent convergence, reduces uncertainty of the attack source, and improves the anti-jamming capability.

Description

technical field [0001] The invention belongs to the technical field of network security, in particular to an attack source tracking method for a distributed denial of service (DDoS) attack in a wireless sensor network. Background technique [0002] As the product of the combination of computer, communication and sensor technology, wireless sensor network has great application prospects in many fields such as national defense and military, environmental detection, traffic management and so on. Recently, the Internet of Things, which has attracted much attention from the world and has become one of the five major network trends in the future, is one of the key technologies for realizing it, which is the wireless sensor network, which also makes the wireless sensor network an active research branch in the field of computer science. [0003] The wireless sensor network is composed of a large number of micro sensor nodes deployed in the monitoring area, and forms a multi-hop ...
