I have updated my #OpenSSL #PQC #benchmark after realising how to get #SecP256r1MLKEM768 and #SecP384r1MLKEM1024 as groups for #TLS

Turns out the performance hit of using PQC #HPKE instead of just the #ECC is neglectable

Benchmarking post quantum cryptography with OpenSSL 3.5: X25519MLKEM768

This Article can be downloaded as PDF file. Generated with AsciiDoctor-PDF UPDATE (20250914): It turned out that s_time did have problems with the new PQC TLS Groups. I found a workaround and added a new Benchmark for all TLS1.3 Groups. Benchmarking OpenSSL and Post Quantum Cryptography: X25519MLKEM768 Since version 3.5, OpenSSL natively supports PQC keys and signatures. There is no need to use OQS-Provider as an provider to use PQC signatures and KEMs anymore.

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.
