[Abstract]:Wireless sensor networks (WSN(Wireless Sensor Networks) are widely used in military, production, medical and other aspects, but many sensor networks are deployed in a harsh and open environment, there are a variety of threats. In some application scenarios, in order to prevent information leakage, network paralysis and other accidents, there are high requirements for its security, but many current routing protocols are assumed to run in a secure environment, and lack of consideration in attack defense. Routing protocol is the foundation of wireless sensor network, so the attack of routing protocol seriously restricts the operation of wireless sensor network under the bad environment. This paper mainly focuses on routing layer attacks, introduces several common routing attacks, and studies two typical routing attacks, wormhole attacks and black hole attacks. Wormhole nodes communicate secretly through "tunnels" formed by private links with high bandwidth and low delay. Malicious nodes can attract large numbers of packets and transmit them through tunnels to collusion nodes to destroy the network topology. According to wormhole attack characteristics, this paper improves the existing method of detecting wormhole by using connected information, and adds several detection characteristics, and proposes a ATIDA detection algorithm for wormhole attack. At the same time, a mobile beacon node is introduced to locate the wormhole node. At the same time, the superiority of the algorithm in detection rate and location error is verified by building the simulation platform under NS-2. Black hole attack refers to a malicious node that claims that it has more residual energy, reaches the destination node or the destination node in one hop, after attracting data packets, discards and does not forward, resulting in a transmission void. In this paper, a location information based trapping detection algorithm, BTCOLI, is designed in this paper. The black hole node is found, authenticated and location detected by using the non-existent destination node as bait, so that malicious nodes can be eliminated. At the same time, a preshared symmetric key is added to provide a HMAC message verification mechanism to prevent malicious nodes from joining the network. Finally, the superiority of the algorithm in the detection rate is verified by building the simulation platform under NS-2.
