About CCSD

Research that strengthens technological sovereignty

The Center for Cryptography and Distributed Systems (CCSD) at the University of Buenos Aires develops technologies and techniques aimed at ensuring the confidentiality, integrity, and authenticity of information in strategic sectors.

Our purpose is to be a reference in the application of cryptographic tools to strengthen system security, generating knowledge, researching secure and efficient technologies, and promoting training and collaboration with public and private organizations.

We drive the development of secure and scalable cryptographic solutions and distributed systems, strengthening the digital infrastructure of Argentina and the region.

Specific objectives

What drives us

Four pillars that guide our daily work and strategic partnerships.

01
Research in cryptography and distributed systems
We generate original knowledge on cryptographic protocols, proof systems, and consensus mechanisms applicable to real-world environments.
02
Academic training and development
We foster the training of students, researchers, and professionals in applied cryptography, digital security, and distributed systems.
03
Engagement with strategic sectors
We collaborate with public agencies and private companies to transfer knowledge and ensure our research has concrete impact.
04
Knowledge transfer and industry
We translate academic results into practical solutions, collaborating with the national and international technology industry.
Research lines

What we work on

Six active research lines spanning from post-quantum security to privacy in artificial intelligence.

01
Post-quantum cryptography
We investigate the impact of quantum computers on current cryptographic algorithms and develop schemes resistant to quantum attacks.
Lattices NIST PQC Kyber
02
Efficient encryption for constrained environments
We design encryption algorithms optimized for devices with limited computing, memory, and energy resources.
Lightweight AES ChaCha20
03
Blockchain and government transparency
We study blockchain applications to improve transparency, traceability, and auditability in government agencies.
Smart Contracts Audit DLT
04
Consensus and propagation in distributed networks
We analyze consensus algorithms and information propagation mechanisms in distributed environments with Byzantine fault tolerance.
BFT PoS Gossip
05
Internet of Things security
We address the security challenges of IoT networks: lightweight authentication, secure channels, and key management in embedded devices.
IoT TLS DTLS
06
Privacy in artificial intelligence
We develop differential privacy techniques, federated learning, and secure multiparty computation applied to AI models.
MPC Federated Learning DP
