  3. 2. EzMole: A new prototype for securing public Wi-Fi connections

    Master-uppsats, Luleå tekniska universitet/Datavetenskap

    Författare :Rickard Karlsson; [2017]
    Nyckelord :EzMole; Wi-Fi; wifi; Internet of Things; IoT; security; vulnerability assessment; access point; Internet; public Wi-Fi;

    Sammanfattning : When public Wi-Fi networks are being used, it can be hard to know who else that is using the same network or is monitoring the traffic that is traveling across the network. If the network is public and unencrypted anyone can monitor the traffic and to use these networks for work can be very risky. LÄS MER
