2019 – 2022 - Science DMZ - Multilayer SDN Project.

Coordinator: Tereza Cristina Melo de Brito Carvalho
Description: Research project on specialized network infrastructures in a laboratory or campus, focused on the movement of e-Science (Big Data) data, with policies and configurations different from those existing in the production network, based on SDN technology. Project certified by the National Education and Research Network on 04/05/2023.

2017 – 2017 - Secure hardware to support SDN in the context of IoT (Research Grant Abroad).

Coordinator: Cíntia Borges Margi
Description: Wireless sensor networks are a valuable technology for the development of applications in various areas, such as environmental, industrial and urban monitoring, health and agriculture. There is no single definition for the Internet of Things, but most agree that it consists of devices capable of sensing/actuation, communication, and processing. Thus, wireless sensor networks (WSNs) become a key technology for the Internet of Things, and research on WSNs should provide a good foundation for developing the Internet of Things. Considering the challenges of different protocols and technologies at the link layer, with limited device resources and security requirements, current research problems address secure communication between wireless sensor network devices and network resource management. The main objective in my current work is the design and validation of a framework of basic communication, security, and resource management services for the Internet of Things, considering the software-defined networking (SDN) paradigm, in order to provide a flexible solution. Security services for embedded devices could benefit from hardware implementation, given the resource-constrained nature of these devices. Thus, the first objective for this project is related to the research and development of an architecture that includes devices based on post-quantum security for the Internet of Things, which requires the complementary knowledge of the research group I am part of at USP and EISEC/TUM. The second objective regarding this project is to formalize and strengthen the link between USP and EISEC/TUM.

2016 – 2019 - Communication, security and management in wireless sensor networks (Research Productivity Grant).

Coordinator: Cíntia Borges Margi
Description: The objectives are the design, implementation, modeling and evaluation of communication protocols that provide basic security services for wireless sensor networks and heterogeneous wireless networks, as well as their integration with wired networks, considering the paradigm of software-defined networking (SDN). The proposed protocols should include secure admission control, data authentication and confidentiality for both end users and SDN-compatible devices. They should also allow communication with mobile devices (such as robots), which can act as data collectors or request assistance from static devices to fulfill their mission. The framework of secure communication protocols will provide a flexible solution, facilitating the adaptation of wireless sensor networks and heterogeneous wireless networks to possible topology changes and reconfiguration for the execution of new tasks, and guaranteeing the associated security services.

2014 – 2016 - Secure integration of heterogeneous wireless networks through Software-Defined Networks.

Coordinator: Cíntia Borges Margi
Description: Wireless networks are valuable technologies for the development of applications in various areas, from environmental monitoring to social networks. Characteristics such as mobility and heterogeneity of the network and devices present new challenges to be overcome for the implementation of communication protocols. This proposal aims to design and implement protocols that provide basic security services for heterogeneous wireless networks, as well as Wireless Sensor Networks, considering the software-defined networking paradigm. OpenFlow is the basic building block in the development of this proposal and, as far as we could assess, it is the first to address security services in this context. Our goal is to include services such as secure admission control, data authentication, and confidentiality for both end users and OpenFlow devices. Thus, we will have a flexible solution that facilitates the adaptation of heterogeneous wireless networks to possible topology changes and reconfiguration for the execution of new tasks, guaranteeing the associated security services.

2013 – 2015 - Science DMZ.

Coordinator: Tereza Cristina Melo de Brito Carvalho
Description: Develop optimized DTNs (Data Transfer Nodes) for transferring Big Data datasets over high-latency networks, using a Science DMZ network architecture, and deploy the developed prototypes in selected campus network environments, with the goal of validating the proposal in real-world use cases with user institutions, in conjunction with RNP. Develop and deploy a monitoring and integration infrastructure for Science DMZs with services of the National Research and Education Network (RNP). Interconnect the Science DMZs of selected institutions, implementing the 'superfacility' concept to maximize scientific research.
