The Internet of Things (IoT) - global connectivity between all kinds of embedded devices and servers - is opening new opportunities for everyday applications. Essential enablers for the IoT are the secure and authenticated connections between things and servers. However, existing solutions for setting up thing-to-server authentication, based e.g. on passwords, trusted certification authorities, or physical connection, are not feasible when servers are far away and things do not have interfaces for inputting passwords or secrets keys. This paper analyses challenges and approaches for security pairing these interface restricted globally distributed things. We explore how mediating devices, such as smartphones, can be used to establish security connections. Particularly, we contribute by analysing how user-friendly security establishment approaches - out-of-band and unauthenticated location-based pairing - can be applied in situations where counterparty is far away or has incompatible interfaces.
