DoS detection system of 6LoWPAN sensing network

Abstract

The invention belongs to the field of security of a wireless sensing network, and provides a DoS detection system of a 6LoWPAN sensing network. The system employs a layered design and is divided into a perception layer, an adaptation layer and a network layer. The perception layer acquires correlation data from a real sensing world and transmits the data to the adaptation layer. The adaptation layer performs header compression, MAC address conversion and address registration. The network layer carries out performance management, state management and security management on the system. According to the invention, the influence of secondary factors on classification performance is reduced; dimensions are decreased, data redundancy information is reduced, and computation is reduced; and the classification performance of a support vector machine is improved, and the real-time performance of intrusion detection and the intrusion detection precision are enhanced.

Description

technical field [0001] The invention relates to the field of wireless sensor network security, in particular to a DoS detection system of a 6LoWPAN sensor network. Background technique [0002] Wireless devices based on the 6LoWPAN (IPv6 over Low-Power Wireless Personal Area Networks) protocol have some inherent disadvantages, such as limited power, processor, memory space, etc., and unreliable communication in terms of loss rate and collision . Attackers can make full use of these weaknesses to launch attacks on wireless sensor networks. Especially denial of service (DoS, Denial Of Service) attack, DoS attack has a very adverse effect on distributed wireless sensor network communication. At present, there is no security strategy for DoS attacks on wireless sensor networks. This project is to provide a system for detecting DoS attacks on distributed wireless sensor networks. [0003] DoS attacks can be initiated remotely with only commands and advanced tools. Attackers ca...
