74. Research on DoS Attacks and Resist Method Based on 4-way Handshake in 802.11i

As the transmission medium is open, the use of wireless LAN communication requires higher performance and better security. By analyzing the latest generation of wireless LAN security protocols in 802.11i, four-way handshake agreement was introduced, two against the DoS attacks. The first four-way handshake based on fake news of a DoS attack was initiated, proposing added authentication solution. Robust security on the second associated information was proposed by modifying the Robust Security Network Information Element (RSN IE) elements in the important position and launching DoS attacks on the proposed four-way handshake process to improve it. Through analysis, the proposed method can effectively prevent DoS attacks from occurring, to a greater extent to improve the effectiveness of wireless data transmission.
