A Study of Secure Communications in WiFi Networks
Along with the explosive increase in Smartphones, users have come to install Access Points (APs) that enable easy and fast wireless access to the Internet at home or a place of business without any restrictions. However, rogue APs that are installed by attackers with a view to obtaining users' confidential information have become great threats to wireless Internet security. A method that can be commonly used in web services to prevent hackers' attacks on Wi-Fi networks with low security is encrypting the data exchanged in HTTP protocols using Secure Socket Layers (SSLs) to ensure data confidentiality in communication. However, even when SSLs are used, users' confidential information can be easily extracted using Man In The Middle (MITM) attacks.
