I'm excited to announce that our "MAESTRO" paper has been accepted at USENIX Security 2025.
This work resulted from collaborative research involving researchers based in 4 different countries. Now I have a good reason to visit those countries for more discussion and beer.

Seems all Crypto 2025 authors have submitted their cameraready papers - www.iacr.org/cryptodb/dat...
In total, 155 papers (new record, but acceptance rate is still low), almost 30 of them about ZK (both theory and practice). The practice papers were mostly available on eprint before, so no surprises

Very excited to be a part of this!
Super pleased to see that Zama has just announced the first recipients of the Zama Cryptanalysis Grants.
www.zama.ai/post/announc...
The projects supported cover security of FHE, MPC, TEEs and ZK.
The teams getting the grants represent some of the leading experts in their respective fields.

For those interested, Real-World MPC, the 4th Annual FHE Conference on fully Homomorphic Encryption and the 3rd Annual Real-World Post-Quantum Cryptography Workshop will be hosting co-located events in Sofia around the same time as RWC 2025. We highly recommend checking them out!
