Secure Hotspot with Multi-Factor Authentication through NFC on Smartphones
Abstract— Many today enterprises attempt to protect their wireless networks from security threats. Another layer of security is typically added to verify users when connecting to a wireless network. One of the wellknown enterprise authentication methods includes WPA2 Enterprise with 802.1X standard, which uses the EAP framework to enable user authentication. Deploying WPA2-Enterprise requires a RADIUS server for handling the task of authenticating access. However, credentials management for all users is a hassle for administrators. Strong authentication processes also require more and more certain actions from users. To enhance security for both users and wireless networks, this research thus presents an approach of Wi-Fi hotspot authentication by adopting MFA technique in addition to NFC utilization for credential information exchange. The implementation is developed on NFC-enabled Android smartphones through network model based on WPA2-802.1X authentication with EAP-TLS. The benefits of the proposed method would be the ease of Wi-Fi configuration and simplicity of internet access as reported in the experimental result.
