The Information Security Group (In French: Groupe Sécurité de l'Information - GSI) was launched by Prof. Gildas Avoine in 2008 in the Department of Computing Science and Engineering of the Université catholique de Louvain, located in Louvain-la-Neuve, Belgium. It offers an active research environment to improve the current state of information security, through research and teaching activities.

With background from computer science, telecommunication, and mathematics, members of the GSI address many aspects of information security especially applied cryptography. Their ongoing research concerns cryptographic protocols, theoretical and practical attacks, time-memory trade-offs, security analysis of RFID solutions including (but not limited to) authentication, privacy, relay attacks, and pseudo-random generators.

Beyond its academic activities, the research group is concerned by industrial needs and provides training, consulting, and auditing. It is also involved in industrial partnerships through research projects.

The group is proud to maintain the RFID Security and Privacy Lounge, a scientific website created in 2004 that references about 400 research papers and 750 members are registred to its mailing list.
