For the first time in ages, new challenges are being added to CryptoHack. To make up for lost time we're adding 50 new challenges including two whole new sections dedicated to zero-knowledge proofs and isogenies. blog.cryptohack.org/new-challenges…

NIST PQC5: FIPS 203 (Kyber) and 204 (Dilithium) will have relatively minor but compatibility-breaking changes. FIPS 205 (SPHINCS+) probably not. The full slides should be online tomorrow at ( csrc.nist.gov/events/2024/fi… ) and the final specs are due this summer. (Pictures: FIPS 204.)

The wait is over! Simon's (@merzsp) frying pan is piping hot and ready to sear us some delicious SCALLOPs, tomorrow at 17pm CET, for the premiere of the fourth season of The Isogeny Club! More info: isogeny.club

Happy to announce that ECC 2024, the 25th Workshop on Elliptic Curve Cryptography, will take place in Taipei, Taiwan Oct 30 - Nov 01, 2024. The workshop will be preceeded by an autumn school on isogenies. For more see troll.iis.sinica.edu.tw/ecc24/index.sh… You can sign up up for annoucements

AES-128 with TFHE-rs in 20 seconds, using Bristol MAND format and 112 threads. See github.com/CryptoPenguin1…

Get ready for Season Three... more info: isogeny.club

PQC standards are out... FIPS 203, Module-Lattice-Based Key-Encapsulation Mechanism Standard FIPS 204, Module-Lattice-Based Digital Signature Standard FIPS 205, Stateless Hash-Based Digital Signature Standard

"FHE should not be seen as a simple encryption algorithm with special properties ready for simplistic deployment, just as textbook RSA should not be seen as a simple encryption algorithm ready for immediate deployment. FHE needs to be seen within the context of a protocol which provides a cryptographic service. Thus, one needs to combine FHE with other cryptographic primitives and ideas, and one needs to think holistically about the entire system security."

@AlexanderMay10 Feeling fortunate to be able to contribute.

@cryptopenguin15 Nice, congratulations. Blocksize quite smaller than estimated, interesting. Fine for you if we add your Lund University affiliation on our webpage?

New week, new #kyber challenges solved on bochum-challeng.es/challenges/kyb…. Congratulations to @cryptopenguin15 for breaking Kyber-144 (15h), and to Alexander Karenin for cracking Kyber-176 (76h). 😳
