WiFi networks, which have been widely used along with the explosive increases in the supply of smartphones, can provide high network speeds but cannot prevent user information spills though rogue Access Points (APs). Therefore, the present paper proposes a method to exchange SSL session keys through more secure 3G networks to be used in WiFi networks in order to prevent such spills. In the proposed method, only those session keys to be used in SSLs are exchanged through 3G networks, and the remaining application data is transferred through WiFi networks. Therefore, attacks by rogue APs can be prevented with sufficient use of the speedy and efficient WiFi networks.
