The Hash Function BLAKE (2015): book about the hash function BLAKE, published by Springer
NORX (2014): authenticated cipher candidate in the CAESAR competition
Password Hashing Competition (2013-2015): open competition that selected Argon2 as a winner
BLAKE2 (2013): hash function faster than SHA-2 and SHA-3, available in OpenSSL, Sodium, Crypto++, etc.
Cryptography Coding Standard (2013-): coding rules to prevent common weaknesses in cryptography software

L’AHTI est une association née en 2000 pour encourager les travaux sur l’histoire des télécommunications et de l’informatique (TIC).

Elle a été créée à l’initiative de François du Castel et Michel Atten qui venaient de terminer un ouvrage sur l’Histoire des Ecoles supérieures de télécommunications, 1840-1997. De nombreuses personnalités du monde des TIC ont été consultées et l’AHTI a finalement été constituée en regroupant des anciens acteurs du secteur (de France Télécom bien sur, mais aussi de Bull, d’IBM, d’Alcatel, de SSII) et des historiens spécialisés du domaine.

NaCl (pronounced "salt") is a new easy-to-use high-speed software library for network communication, encryption, decryption, signatures, etc. NaCl's goal is to provide all of the core operations needed to build higher-level cryptographic tools.

The current version of NaCl supports C and C++. Support for Python is a high priority.

While focusing on network security monitoring, Bro provides a comprehensive platform for more general network traffic analysis as well. Well grounded in more than 15 years of research, Bro has successfully bridged the traditional gap between academia and operations since its inception. Today, it is relied upon operationally in particular by many scientific environments for securing their cyberinfrastructure. Bro's user community includes major universities, research labs, supercomputing centers, and open-science communities.

ECRYPT-CSA is a Coordination & Support Action funded by the European Union's H2020 programme. The project consists of four academic and one industrial partner.
ECRYPT-NET is a research network of six universities and two companies, as well as 7 associated companies, funded by a Marie Skłodowska-Curie ITN (Integrated Training Network) grant.
