What a great set of awardees for the #Levchin prize 2026

🏆 Whitfield Diffie and Martin Hellman for the invention (and publication 🤭) of Public Key Cryptography 🔐

🏆 The Tamarin team for the developement of the Tamarin prover and its use in verifying security protocols

Well-deserved 👏

#RealWorldCrypto

i wonder if the #iacr #levchin #prize at #realworldcrypto this year goes to trump?

here's the paper for the #RealWorldCrypto talk from yesterday where they extracted an AES key modulated by interference onto the bluetooth signal: https://ia.cr/2025/559

#rwc #crypto #sidechannels

wow, the last session of todays #RealWorldCrypto on #sidechannels was a blast, first E. Ronen shows microarchitectural weird gates built out of branch-prediction and addresses in cache, which he then uses to run game of life, and build a timer with accuracy of 5 cycles to deploy in timing side chan attacks. #rwc2025 1/3

I'm now leaving for #realworldcrypto in Sofia, Bulgaria. 😃

There is even a small(!) Chance I might find a new job there. 😊

Speaking of which: If you are looking for a cryptographer (PhD) in the Netherlands who is specialized on provably secure post-quantum key exchange protocols (but interested in much more): Talk to me! #getfedihired

#rwc #RWC2025 #RWC25

i was just told that it is deliberate that #realworldcrypto is not #streaming the event. apparently this is a controversial discussion every time. but they also decided next year will be streamed again... what i wonder though, why the secrecy? why not say it out on the webpage, sorry folks no streaming because of <reason>.

anyway, looking forward to the recordings, and next years streaming

#iacr

If anyone from #RWC (or anyone in general) is still hanging around tomorrow night and wants to check out #Toronto's long running #Infosec meetup #TASK, there will be talks on hacking games and "AI" threat detection. We decamp to a pub afterwards. https://www.task.to/schedule/v3f7p4b6zhdyhz42w5flrfk9042n1b-awj77-rdbak-fdc5x-26fwb-7b2l5-bt7nz-d86l5-k57sz-93dff #RealWorldCrypto

seriously considering sponsoring live streaming (and archival) for the next #rwc when it is in europe... if anyone is interested, pls chip in, we have the hw and the personal we only need to cover travel and accommodation.

anyone have a URL for a livestream or recordings from #realworldcrypto2024? if it exists they are very good at keeping it confidential.... #realworldcrypto #rwc2024

While I couldn't be at the Open Source Cryptography Workshop or #RealWorldCrypto to speak and collaborate in-person (because I got COVID again, woo), I recorded my Workshop talk about #Rustls-FFI and #curl, which just played there in Tokyo.

I've embedded the recording in my blogpost here: https://insufficient.coffee/2023/03/30/opensource-crypto-workshop-rustls-ffi/

I got some good live questions about using multiple layers of statically (or dynamically) linked FFI libraries, and about compiling rustls-ffi on systems unsupported by #ring.
