Prevention research of cracking WPA-PSK key based on GPU

Along with the advancing times and the technological development, WLAN technology has been widely applied in our daily work. Apart from the convenience it has brought, it has also triggered several problems. Aimed at WPA encryption method widely used in wireless network, and under the GPU-based highspeed cracking WPA method verified previously, this paper proposes a new defense strategy, analyzes the feasibility of this strategy, carries out simulation experiment to validate the defense strategy, proving that this policy can greatly improve the security of WPA encryption. It has certain significance in guiding the development of wireless networks.
