With an ever increasing number of everyday objects from our homes, workplaces and even from our wardrobes, getting connected to the Internet, known as the ‘Internet of Things’ (IoT), researchers from the University of Southampton have identified easy-to-use techniques to configure IoT objects, to make them more secure and hence help protect them from online attacks.
This increased connectivity brings additional risk. Setting personalised and strong passwords when connecting new devices to the Internet, for example through our home Wi-Fi networks, can mitigate such risks. However, many IoT devices have limited interfaces: just a few buttons (if any at all) and light indicators, making it challenging for users to configure them. If secure configuration becomes complicated, users may choose easier, less secure options that leave their devices vulnerable.
Southampton researchers compared four interaction techniques for the configuration of IoT devices, looking for methods that allowed security, but were quick and easy to use. All four techniques used the smartphone touchscreen to let users enter secure passwords.
