The Design Of Highly Reliable Embedded System With WLAN Jamming Attack

In recent years, with the rapid development of W ireless Local Area Network(WLAN) technology and the embedded system technology,mobile intelligent devices(such as smart phones and tablets)are more and more common in our daily life.It makes our life more convenient.People can get many things they need through the internet. The mobile network is easy to connect, this makes the WlAN security issues prominent.In this paper, we made a study on the physical layer and MAC layer, analyzed the WLAN offensive and defensive technology, also we studied the dual-FLASH setup and the embedded system technology. We designed a highly reliable embedded system with WLAN jamming attack using PXA255 as the core processor. We introduced the hardware-design and software-design. We designed the dual-FLASH setup module in the hardware-design to ensure the reliability of the whole system. We programmed to implement the haredware to listen and attack the WLAN when we need. We can make the normal users to disconnect with the AP through attacking. Then we influenced the normal users' normal access to the internet.
