We are pleased to announce that the Trusted Certificate Service (TCS) has been restored after migration to a new provider. It is now provided by the Greek academic certification authority HARICA.

This year, colleagues from CESNET took part in the largest international cyber security exercise Locked Shields 2025, which took place on 5. - Locked Down Shields 2020, held on 9 May under the leadership of the NATO Cooperative Cyber Defence Centre of Excellence (CCDCOE).

CESNET's OptiLAB recently tested a newly acquired TOSHIBA LD quantum key distribution (QKD) system that represents the cutting edge of secure quantum communication. This system enables the generation and distribution of cryptographic keys based on quantum phenomena, thus ensuring an extremely high level of security against eavesdropping. The acquisition of the QKD system is part of a broader strategy to develop a quantum secure infrastructure and its deployment opens up new opportunities for research in quantum cryptography and single photon physics.

On the website of the IPv6 Day 2025 conference, which will take place on 6 June at the National Technical Library, you can find the complete programme of this year's. A busy day of lectures, news and inspiration from the world of IPv6 awaits you.
Feel free to register via the online form  – it won't work without registration.

Are you wondering what violates not only Einstein's laws but also common sense? Come to the lecture on 15 May at CESNET and hear the latest news in quantum cryptography. More information here. 

On Friday, 6 June 2025, the next edition of the traditional IPv6 Day conference will take place, to which we cordially invite you. Come and get inspired, hear the latest news and meet members of the community. The event is organized together with our partners CZ.NIC and NIX.CZ at the National Technical Library in Prague.
