SureThing: Device Location Certification for the Internet of Things


By Miguel Pardal, Instituto Superior Técnico, University of Lisbon & INESC-ID

The scale and geographic dispersion of the Internet of Things (IoT) will surpass the size of the current day Internet in, at least, 3 orders of magnitude. The IoT will be the largest and most widely distributed system ever, with a multitude of connected sensors and actuators. The current Internet already has some serious, unresolved security problems. Adding physical world autonomous connections brings even more concerns about attacks and their consequences to people and goods.
The SureThing project (, recently started, is addressing an IoT security need:
creating and validating location certificates. The project’s goal is to allow for constrained devices, needed in the provisioning of IoT services, to obtain proof of their location or to request proof of location to other devices. The certificates issued using the SureThing framework will contain location data, obtained and verified using: WiFi and Bluetooth fingerprinting, and ambience sensing.
The SureThing framework will allow developers to choose between faster location proofs and more reliable proofs, which will be digitally signed and kept in a ledger. The witness models – providing a validation role for other devices at the same location – will play an important role, particularly when only limited cryptographic mechanisms are available.
