Santa's Crypto Get-Together (SantaCrypt) started in December 2001 as the first annual Czech and Slovak workshop aiming to facilitate closer cooperation of professionals working in the field of applied cryptography and related areas of security. This get-together of experts is organised in order to foster exchange of information and ideas on past, ongoing, and also future projects. We recognise the need of experts meeting their colleagues without the hassle of taking care of their (potential) customers, bosses and other distracting forces. ;-) The workshop is run in English in the first day and then Czech and Slovak the second day.

There will be invited lectures:

• Peeter Laud, Cybernetica, Estonsko: Efficient Two-Party ML-DSA Protocol,
• Lenka Mareková & Kenny Paterson, ETH Zurich, CH: Four Attacks and a Proof for Telegram,
• Vadim Lyubashevsky, IBM Research, CH: On lattice cryptography or zero-knowledge,
• Tomáš Sušánka, Trezor, ČR: On practical deployment of cryptographic systems,
• Tomas Rosa, Raiffeisenbank & MFF UK, ČR: Elektronické útoky v terénu rozhraní PC - modely a zneužití,
• Marek Sýs, FI MU, Brno, ČR: Lattice-based attacks and cryptography.
