• (2016-2017 / Portugal) Internship: Telecommunications Institute, University of Aveiro, Portugal

PhD Student

Doctoral internship aimed to discuss and develop hardware security techniques for a SDN switch operating with a Workspace-based architecture (ETArch). First, I investigated and implemented crypto mechanisms, including Montgomery multiplication, intending to add them to a future switch. Then, we decide to move the efforts to the forwarding engine of this switch itself.  A NetFPGA 1G board was used at first. I simulated a series of VHDL coded blocks that, afterwards, became Datapaths of the switch’s forwarding plane.

• (2014-2018 / Brazil) R&D: A2RCON – Adaptable Architecture for Convergent Networks

PhD Student

The project aimed to develop a reconfigurable architecture for Future Internet, where SDN mechanisms are applied in the network infrastructure to provide efficient video support. My duties were to be working as a hardware designer to propose a way to enable the communication between application requirements and a non-TCP/IP link layer (from the Entity Title Architecture - ETArch). I designed a switch forwarding engine based on virtual data planes with a set of hardware implemented functions and specified a protocol to configurate this switch. Also, I provided a hardware abstraction layer to be used by comunnicating entities. The whole system was prototyped in reconfigurable hardware, using a low cost FPGA of the family Altera Cyclone II. To bypass MAC and Ethernet controllers, switch ports were connected with external RJ45 transceivers completely raw of protocols. Hence, all the hardware manipulation is written in ETArch specifications, including a novel medium access controller.

• (2013-2014 / Brazil) R&D: Universities Cooperation Network to Develop Scientific and Technical Research in Electronic Systems applied to Security

PhD Student

A series of initiatives aimed to build a research partnership between two Brazilian Universities focused on electronics applied to defense, including research on hardware security in network equipments. I mainly had to evaluate whether some hardware implemented mechanism could be added at the link layer of a Future Internet architecture to improve security at the link layer level. I proposed and implemented in VHDL a mechanism to have hardware programmable Workspaces in a way that crypto algorithms could be inserted if needed. Also, I worked by training students to prototype using Xilinx and Altera’s FPGAs.

• (2010-2012 / Brazil) R&D: HASH – Protocol for High-Availability Architectures

MSc Student

This project aimed to address and circumvent the Split-Brain problem in High Availability protocolos, such as VRRP. My tast was to develop a high availability protocol with no Split-Brain condition to operate in IPv4 networks and, afterwards, be compatible with ETArch to Future Internet. As a M.Sc. student, I specified the High Availability Router Protocol (HARP). The protocol spec includes environment, services, vocabulary, format and procedure rules. I built a FSM and wrote a verification model with the specification language TLA+. I implemented the protocol in VHDL simulated with Modelsim, and built a network based on the NIOS II processor to validate the protocol operation. To integrate the protocol and processor cores, I also wrote a VHDL Ethernet interface controller to act between CPU and the I/O subsystem.
