»NIST standardisiert ein leichtgewichtiges Kryptografieverfahren für IoT-Geräte:
Ascon ist ein leichtgewichtiges Kryptografieverfahren, das insbesondere für IoT-Geräte wie RFID-Tags gedacht ist. NIST hat das Verfahren nun standardisiert.«Ich habe absolut keine Ahnung von IoT aber spannend. Es sind leider sehr viele IoT-Tools, die im allgemeinen erhältlich sind, sehr unsicher im Web.

#Qualys needs to update their TLS client test to support the new signature algorithms and named groups. There are a fair number of "unknown" entries with #OpenSSL 3.5. https://clienttest.ssllabs.com:8443/ssltest/viewMyClient.html

So looking through some old projects I’ve had lying around, I ran into something I started (and never even really wrote anything) about steganography. This led me down a bit of rabbit-hole and I now have a slightly better understanding of some components of ML-KEM (aka. #Kyber).
Both the public key and the ciphertext are for the most part long sequences of integers modulo 3329 that are effectively indistinguishable from random integers out of that range.
Of course they are obvious to distinguish from random bitstrings, but the easiest way to fix that would be to just view them as numbers in base 3329, re-encode them to base 2 and work from there… So that might be one thing I could look into now.
The alternative is to see whether there is a sufficiently hard to detect way to change some of the representatives of the field-elements… It might be easier to implement if, if not easier from a mathematical perspective, but would also let the possibility of slightly compressing the public-key and ciphertext by about 2.5% in length lie on the table.
In any case, this is something that might be worthwhile for practical use-cases… 🤔
