Award
We are proud to announce the winners of the 2024 IACR Test-of-Time Award for Crypto.
The IACR Test-of-Time Award honors papers published at the 3 IACR flagship conferences 15 years ago which have had a lasting impact on the field.
The Test-of-Time award for Crypto 2010 is awarded to the following two papers:
Factorization of a 768-bit RSA modulus, by Thorsten Kleinjung, Kazumaro Aoki, Jens Franke, Arjen K. Lenstra, Emmanuel Thomé, Joppe W. Bos, Pierrick Gaudry, Alexander Kruppa, Peter L. Montgomery, Dag Arne Osvik, Herman te Riele, Andrey Timofeev and Paul Zimmermann.
For the landmark factorization of a 768-bit RSA modulus, guiding the deprecation of RSA-1024 and advancing practical cryptanalysis.
Cryptographic Extraction and Key Derivation: The HKDF Scheme, by Hugo Krawczyk.
For formalizing key derivation and introducing HKDF, a widely adopted and standardized extract-then-expand scheme.

Congratulations to all winners!
