Homomorphic Techniques for Secure Computation
Speaker: Pedro Capitão (Slides)
Bio: Pedro Capitão came into contact with cryptography while studying mathematics at Técnico Lisboa and moved on to become a PhD student in the Cryptology Group at CWI Amsterdam. His research focuses on topics related to secure multi-party computation, such as homomorphic secret sharing, homomorphic encryption and zero-knowledge proofs.
Abstract: Secure multi-party computation (MPC) allows two or more parties to jointly evaluate a function on their inputs, with the guarantee that the result is correct and the inputs remain private. In this talk I will go over some classical and modern approaches to building MPC protocols, while discussing their efficiency and highlighting the power of tools such as homomorphic encryption and homomorphic secret sharing, as well as their limitations.
Mathematical foundations of the SditH signature scheme

Abstract: As quantum computers pose a growing threat to traditional digital security, the cryptography community is working to build reliable post-quantum alternatives. One promising direction is code-based cryptography, which relies on the fundamental difficulty of decoding random linear codes. In this talk, we will explore the SDitH (Syndrome-Decoding-in-the-Head) signature scheme, a candidate currently in the Third Round of the Additional Digital Signatures PQC Standardization Process. We will first present the mathematical problem on which the scheme is based, and then continue with its architecture using the VOLEitH framework, looking at the core mathematical foundations and theoretical design choices that hold the scheme together.
Quantum Communications in Portugal
Speaker: Catarina Bastos (Slides)
Abstract: In this talk I will present the status on quantum communications in Portugal. From the Laboratory to the operational network what has been done through the main actors in industry, academia and public institutions in Portugal. Starting with the development of national technology under a European Defence project, DISCRETION, to the deployment of the first EuroQCI (the European Quantum Communication Infrastructure) segment in Portugal, PTQCI. I will show that quantum communications is no longer a science project, but it is on the heart of sovereignty in Europe.
