Bidding simulation process in which different excel files containing the proposal of the interested companies are sent, the server receives the files, decrypts them and returns the winner of the bid.

👨‍💻 🔐 📈 A project based in (Classical) Post-Quantum Cryptography, namely in Lattice-Based Cryptography. This project was built using Jupyter Notebook, SoS (Script of Script) Notebook, Java, Python, Bouncy Castle library, and TeX. The goal of the project was the study and analysis of the CRYSTALS public-key (asymmetric) cryptographic suite.
