About
I am curious about everything since I remember and the will to learn more never disappears. In a world that is constantly changing, it is important to be always updated, especially when we talk about IT, where every day there are new technologies available.
I have studied BSc in Informatics Engineering at University of Minho. These were the most important years in my graduation, where I learned a new way of thinking before new problems. During these years, I followed some tutorials about Web Development that have proved very useful in some projects I was involved.
I am MSc Student Informatics Engineering at University of Minho. My primary interest at the moment is High Performance Computing (HPC) in parallel architectures, which is the topic of my master thesis. But, I’m also interested in other topics like Computer Graphics, Distributed Systems, Web Development and Mobile. I believe that we must be prepared to face several problems, so that we can adapt ourselves to several work circumstances.

Master's Thesis
My master's thesis was developed in High Performance Computing (HPC) field, where it was supervised by Prof. Alberto José Proença (Adviser) and Artur Mariano (Co-adviser). The thesis is entitled 'Towards an efficient lattice basis reduction implementation'.
The security of most digital systems is under serious threats due to major technology breakthroughs we are experienced in nowadays. Lattice-based cryptosystems are one of the most promising post-quantum types of cryptography, since it is believed to be secure against quantum computer attacks. Their security is based on the hardness of the Shortest Vector Problem and Closest Vector Problem.

Integrit
The project aims to implement a background Java Service that is started automatically when the system is turned on. It is a File Verification System on Unix. The service is also able to recover its previous state, by saving its state into a file. It can be started, paused, and stopped at any time with the use of system signals, i.e., HUP and INT.
Every time that someone access a file or directory, it is left a trace. Thus, it is possible to prevent/avoid possible attacks to sensitive information. This project verifies:
- Last access to a directory/file;
- Last time a file was edited;
- New directories/files;
- Deleted directories/files;
- Ownership's changes;
- Group's changes;
- Change of access permissions;
Then, there are done system logs with different levels of danger.

Secure Chat-Server
Secure Chat-Server is a simple chat-room that implements the best cryptographic techniques that should be implemented in secure everyday applications. This project is constituted by two main applications (Client-side and Server-side).
The messages are encrypted and decrypted by the chosen cryptosystem, i.e., CBC. At the beginning of each communication, the key is agreed by the two entities with the Diffie–Hellman key exchange protocol.
Unfortunately, these techniques cannot avoid the well-known man-in-the-middle attack. Thus, it implements digital signatures, where we simulate a Certification Authority (CA) to generate and sign the digital certificates. These digital certificates are managed with X.509 standard for a Public Key Infrastructure (PKI).

3D Graphics Engine
3D Graphics Engine is a C++ engine that is capable of rendering 2D and 3D graphics.
3D Graphics Engine
3D Graphics Engine is a C++ application that uses the OpenGL library. It was developed within the class of Computer Graphics. The project requires two main applications: (1) a generator that generates all the necessary points to render an arbitrary 3D object, i.e., sphere, cube, and (2) a graphics engine that renders the 3D objects from different sources.
These project aims to consolidate the knowledge learned during the classes. The generator is responsible for modelling objects, using surfaces defined analytically, where it generates a GLUT version and a Vertex Buffer Objects (VBO's) version to achieve better performance. In addition, it also generates cubic surfaces, such as Bézier surfaces.
However, the most important techniques are implemented in the graphics engine, which implements geometric transformations, culling, Catmull-Rom curves, illumination effects, textures, atlas textures, pop-up menus, picking, different camera modes (explorer mode / first-person), View Frustum Culling.
The funny part of this project is the graphics engine, that loads all the information to render a scene from a XML file, where each object can have different properties without affect the others.
