Abstract
The Internet of Things is considered an emerging technology with the potential to penetrate all aspects of our lives. However, with great power comes great responsibility and the privacy and security needed for critical infrastructure or sensitive commercial operations is very different than the needs of a Smart Home. Additionally, the available security resources from the private sector are totally different than the ones available to a homeowner. In this context, we developed an open source architecture for IoT which is based on the advantages of a SCADA system and can be easily applied to a Smart Home. This architecture assures a high-security level, even for low technical skills homeowners, with minimal costs.
