Internet of Things (IoT) brings significant challenges to authentication schemes in a scenario with several appliances for a smart house that should be accessed by a technician for maintenance tasks, for instance. An Identity Management (IdM) can be applied in order to easily authenticate a technician that intend to access the appliances from the Internet. However, Internet context is significantly different from IoT, demanding context adaptation to work. Thus, integrate these contexts to allow

The goal is to allow a technician to access an appliance that is not reachable from the Internet, using IdM and without create a single compromising point -a critical entity for security -in the gateway that link the two contexts. The proposal interact two key-based scheme, one for Internet and another for IoT to reach integration between both contexts. A proof-of-concept implementation shows the proposal is feasible and did not affect the message exchanging with up to 1024 bytes and 50 appliances.
