KEKS кодек и криптографические сообщения

Данная статья напоминает о проблемах X.509 PKI и реализаций ASN.1. Предлагает компактный, быстрый, детерминированный, потоковый и простой формат кодирования данных KEKS, а также криптографические сообщения для подписи и шифрования данных с поддержкой пост-квантовых алгоритмов.

The new Internet standard of Hybrid Public Key Encryption has been published as RFC 9180. I am a co-author and was involved in its cryptographic analysis and design. I wrote about this process from my point-of-view as first-time standard co-author. #hpke https://www.benjaminlipp.de/p/hpke-cryptographic-standard/
Hybrid Public Key Encryption: My Involvement in Development and Analysis of a Cryptographic Standard

I am a PhD candidate in the Prosecco research team at Inria Paris. My research focusses on computer-aided cryptography: I have been writing mechanized cryptographic proofs using the CryptoVerif proof assistant, verified implementations with the F* programming language, and have been working on linking CryptoVerif proofs to F* implementations. For one case study on a cryptographic protocol, I got involved into the analysis and development of a new Internet standard, HPKE.
