Abstract
Delving into the architecture and implementation of dynamic trust management in IoT security. It examines the challenges of securing diverse and resource-constrained devices in untrusted environments. The chapter explores the ERATOSTHENES project’s approach to establishing and re-assessing trust scores for devices based on their capabilities, context, prior knowledge, and security guarantees. It discusses key components like the Trust Manager & Broker, Threat Modeling & Risk Assessment module, and Trust Agent, highlighting their role in creating adaptive and resilient IoT systems.
