NIST утвердил стандарт облегчённой криптографии для встроенных устройств

После десяти лет обсуждений и тестирования десятков алгоритмов Национальный институт стандартов и технологий (NIST) утвердил окончательный стандарт «облегчённой криптографии» (lightweight cryptography) для микроконтроллеров, встроенных CPU, слабых FPGA и других устройств с ограниченными аппаратными возможностями, то есть минимальным количеством памяти и вычислительными ресурсами. Принятие стандартов даёт надежду, что современная криптография — идентификаторы, цифровые подписи, шифрование, защита от кибератак — будет поддерживаться на миллиардах устройств Интернета вещей и другой малой электронике, такой как RFID-метки и медицинские имплантаты.

NIST is done standardizing #ASCON, an encryption and hashing algorithm. I count that as a big win for #IoT security, in particular because the last review round's raised concerns were heeded and there is now a 32-bit tag mode usable for applications such as 802.15.4 link-layer security.
Congratulations to the #TUGraz team, whose original work prevailed in a highly competitive selection, and is now the new NIST standard more than 10 years after its inception.

The #Ascon implementations in #Rust are now updated to the changes from the NIST draft.

For AEAD, check out: https://crates.io/crates/ascon-aead
For hash and XOF, check out https://crates.io/crates/ascon-hash

Interesting way to learn a new programming language by implementing a crypto cipher. The standard library was quite helpful to learn some best practices.

My Rust implementations of #Ascon are now part of RustCrypto's https://github.com/RustCrypto/AEADs and https://github.com/RustCrypto/hashes repositories. Thanks to @bascule for starting the discussion and helping with the merge requests.

da bekommt man direkt flashbacks zu den guten alten #anstoss tagen 🥰

This is relevant to my line of work. I shall study up on #ASCON:

For the use of #Ascon as cryptographic hash or as extendable output functions, also checkout https://crates.io/crates/ascon-hash

@campuscodi The need for these confuses me because in 2023 I have a hard time imagining that fitting AES and SHA2 into connection capable microcontrollers on a power budget is difficult. What is my imagination missing?

Wow! Wonderful news. I am a fan of #Ascon (by TU Graz) and it just won the cryptographic competition for lightweight cryptography.

My #Rust implementation of #Ascon, ascon-aead, now also contains an implementation of Ascon-80pq. Details at https://crates.io/crates/ascon-aead
