Security is of paramount importance for the Internet of Things, Industrial Internet of Things, and cloud-based architectures. In this context, the Telematics Lab achieved consolidated research skills useful to define and implement distributed security architectures offering, also in federated and multi-authority scenarios, decoupled authentication and privacy-oriented authorization (i.e., Attribute-Based Access Control with ephemeral user identities) services, lightweight key agreement mechanisms, blockchain-enabled solutions, and flexible architectures providing dynamic and adaptable confidentiality requirements.
