Its goal is to contribute, from a scientific standpoint, to building the mechanisms of a society where everyone can exchange information comfortably.
The lab is a group of experts who study anything related to information security, from cryptography and networks to economics.
Key terms
- Cryptography
- A technology that converts information into an unreadable form by a fixed procedure, so that only people who hold the key can restore it
- Digital signature
- A technology that makes it possible to verify who created electronic data and whether it has been altered along the way
- Denial-of-service (DoS) attack
- An attack that sends a massive amount of traffic or similar requests to make a server or network unusable

The lab studies information security with the goal of contributing, from a scientific standpoint, to building the mechanisms of a society where everyone can exchange information comfortably. It works in three areas: cryptographic theory, network security, and security management.
*Illustrative imageCryptographic Theory and Its Applications
The lab studies the fundamental cryptographic techniques used to conceal information and to verify the identity of a communicating party. Its work covers public-key cryptography, digital signatures, and key management, and it aims to demonstrate uses that only become possible through improvements, and to consolidate its results into general theory.
*Illustrative imageNetwork Security
The lab analyzes threats that arise precisely because networks such as the Internet are open, and studies countermeasures such as attack detection, tracing, response, and avoidance of vulnerabilities. Its themes include finding clues for detecting previously unknown denial-of-service (DoS) attacks.
*Illustrative imageSecurity Management
The lab addresses the overall management of information security, which is difficult because it involves human and social aspects. It studies risk management, security economics, and security psychology through theory and empirical research based on data.
