Current Research Projects and Collaborations

• Automation of Remote Security Bootstrapping Through Named-Data Networking. The current IP's communication model is end-to-end, recipient-oriented, and path-based. These properties are harder to apply in dynamic environments featured by intermittent connectivity, dynamic topologies, and intense node mobility. When plugged into an IP network, the device's protocol stack requires a set of further connectivity configuration procedures to communicate with other nodes, carried out by infrastructure-based network services. IoT systems, however, present new mobility and security requirements that current infrastructure-based network services fail to address due to some reasons. Firstly, in dynamic environments, there is no guarantee that these services will be available when plugging a new device into the network. Secondly, IP forwarding is stateless and has no adaptability of its own, so requiring constant protocol configurations. Thirdly, node mobility demands a simple, flexible, and fast security configuration, not seen in current TLS/SSL-based solutions. Named Data Networking (NDN)'s built-in features can meet these requirements. It is a networked system formed by named entities through which the names stem from those used by applications with semantic meaning and its communication model focuses on the content itself (i.e., what) rather than its location (i.e., where), using directly secured data signed by data producers. However, the need for name assignments and trust configuration in deploying new entities in an NDN network requires systematic solutions to minimize manual operations during NDN configurationsin IoT environments, particularly those formed by remotely-located massive devices. Hence, this project aims to investigate trust management and configuration, remote security bootstrapping, and easy-to-use solutions to support NDN deployment in mobile IoT.

• On supporting Ambient Assisted Living applications through Named-Data Networking and Internet of Things. Among the proposals for new Internet architectures, NDN is the one that has presented the most significant advances and has strong support from industry and academia. Its properties are the ones that most address the requirements of AAL applications, characterized by the use of IoT devices, intense mobility, and communication between different devices. Therefore, this project aims to investigate how the NDN architecture associated with IoT can meet AAL systems requirements and boost the development of AAL applications. When using NDN to support AAL applications, it is crucial to identify and define naming schemes, forwarding models, routing protocols, and security strategies to meet the requirements specified in the scenarios. The expressive semantics of the name, the dynamic definition of forwarding strategies, the development of lightweight routing protocols, and a flexible trust policy characterization can contribute to these goals.

• On Supporting the Internet of Things Through Named Data Networking: Interoperability, security, and mobility. Despite the benefits and potential of the NDN architectures to meet the challenges of communication among network devices in IoT, many R&D issues are still open and in the early stages of discussion. Thus, the main goal of this research is to define and implement architectural elements of NDN that provide native support for the communication of devices in the Internet of Things for interoperability, mobility and security. This general objective results in the following specific objectives: (i) the development of confidentiality and integrity mechanisms for network contents; and (ii) support for the mobility of data producing and consuming nodes; (iii) the definition of an adaptation layer that supports multiple link leveltransmission technologies.
