摘　　要：The Internet of Things (IoT) is an emerging network infrastructure with more than five devices owned by a single user. Wireless connectivity forms the backbone of such infrastructure. IoT uses diverse wireless communication technologies such as IEEE 802.15.4, Wi-Fi, Zigbee, Bluetooth, RFID, BLE (Bluetooth Low Energy), and various other cellular technologies. Wi-Fi is most suitable for IoT Home or office networks. Practically wireless signals do not adhere to the boundaries of the office or home, or organization and impose inherent security risks like information leakage, unauthorized access, other security and privacy threats to networking infrastructure. Therefore Authorization/Association of devices is one of the main security concerns. This paper discusses how unauthorized access to wireless networks (Wi-Fi) can be secured by improving existing WPA2 protocol security.The Internet of Things (IoT) is an emerging network infrastructure with more than five devices owned by a single user.
