The Internet of Things (IoT) encompasses technologies that include devices with computational capabilities, software, and other components that connect and exchange data over the internet or other network systems. This thesis explores the security challenges IoT devices face throughout their lifecycle and demonstrates how these can be effectively managed using the Security-by-Contract (\SxC) paradigm through a Usage Control System (UCS). The UCS employed in this research uses a distributed architecture with a Distributed Hash Table (DHT) and focuses on deployment in home environments, specifically on lightweight systems such as a Raspberry Pi with 8 GB of RAM. This approach aims to address security issues by integrating robust access control mechanisms within constrained devices, enhancing IoT device security in everyday settings.
