Embodiment Construction

[0080] Assume that within a short period of time after the wireless sensor network is deployed, there are no malicious nodes in the network; each node saves its own neighbor table (reachable by one hop) and neighbor table through the neighbor discovery process; the base station keeps The topology of the entire network; the data contains the identity information of the source and target nodes.

[0081] For the convenience of description, we divide the attacks that wireless sensor networks are vulnerable to into external attacks and internal attacks, and accordingly illustrate the specific implementation of the above hybrid intrusion detection method.

[0082] 1. Intrusion detection of external attacks

[0083] External attacks against wireless sensor networks mainly occur at the data link layer, including collision attacks, unfair competition, resource exhaustion attacks, and integrity attacks.

[0084] Collision attack: When the channel is not idle, malicious nodes intentiona...

Abstract

The invention relates to one wireless sensor network mixture intruding test method, which comprises the following steps: integrating multiple test method based on host machine, network, integration and abnormal mode, wherein, according to wireless sensor network property and outer and inner attack and distributing the test task onto sensor points, cluster point and base station point combined with host machine and network.

Description

technical field [0001] The invention is a security protection scheme of a wireless sensor network, which is mainly used to solve various security attacks and security problems suffered by the wireless sensor network, and belongs to the application field of wireless sensor network and information security cross technology. Background technique [0002] Wireless sensor network is a new type of network formed by self-organization of a large number of cheap low-power sensor nodes through wireless multi-hop, widely used in military, medical health, industrial control, environmental monitoring, smart home and other important important occasion. Sensor nodes have the characteristics of small size, poor computing, communication and storage capabilities, powered by disposable batteries that cannot be replaced, and are often deployed in unattended open and harsh environments. Compared with traditional networks and general self-organizing networks (Ad Hoc networks), it is more vulnera...
