This article proposes a new design scheme and hardware implementation of encryption system based on Wi-Fi technology. This system uses a digital chaotic encryption core based on FPGA. The initial key generated by Logistic digital sequence can be used to output stream cipher, by which the plaintexts are encrypted. Then the scheme realizes a safe and reliable information transmission by Wi-Fi module. This paper embeds the scheme into two boards, by which the wireless secure communication between the FPGA board and laptops can be realized. The simulation results show that the system is available.
