WE ARE CESNET
WE UNITE SCIENCE

V úterý 12. listopadu 2025 jsme v pražské kanceláři sdružení CESNET přivítali nejúspěšnější řešitelky a řešitele letošního ročníku soutěže The Catch. Při slavnostním setkání obdrželi pamětní medaile a věcné ceny jako poděkování za svou vytrvalost a vynikající výkony při řešení náročných úloh.

How can we ensure secure digital communication at a time when quantum computers are beginning to gain ground? Czech and Taiwanese experts sought answers to this question during an October research mission to Taiwan – the first Czech mission focused on post-quantum cryptography. The CESNET association was represented by Josef Vojtěch, an expert in quantum communication and optical networks.

The mission aimed to strengthen cooperation in the field of digital security and share experiences with the latest approaches to network and communication protection. The Czech delegation was led by Jan Rada from the National Cyber and Information Security Agency (NÚKIB), with representatives from the Brno University of Technology and the CESNET association also participating.

From September 12 to 14, the unique musical project Threads of Vitality will be presented at the EXPO 2025 world exhibition in Osaka, Japan.
