Nah, I just need more coffee!

When I read “was” I feared the worst. Glad to hear Alfred is alive and kicking (and still having impact).

Two carved wooden heads on a Swiss bridge, both looking startled.

Catching up on recent posts on the CFRG mailing list.

Good luck - hope everything goes smoothly and the course is a hit!

I like it! New mascot for the group.

Do I let this guy stay in the garage or gently remove him to a nice damp bit of garden?

Curve25519 is a false friend. Also isn’t it “defence” rather than “defense”? 🇬🇧

Would it be too salty to say how reassuring it is to find so many new experts in quantum computing and post quantum cryptography suddenly popping up over on LinkedIn?

New reading material dropped.

RWC 2026 call for papers Real World Crypto Symposium

The Call for Contributed Talks is now open for RWC 2026! And the deadline for submissions is now Oct. 10, 2025.

Reading this gave me a lift - we are rapidly progressing to a carbon-free future, at least outside the US (who are being held back by extremist ideology and power of big oil lobbyists).

Wrong pole!

Hello again from mighty Svalbard, 78 degrees North, 125 days of constant sunlight.

Some impressions of Longyearbyen from the last few days.

It’s nearly midnight in Svalbard, and I’m about to try to give an entertaining yet challenging talk at #ArcticCrypt -wish me luck!

Bill Mitchell @askbillmitchell.bsky.social - 3h So yes, I do think I have a better insight than the president of the company. I'll wait while you try to remind me that Signal is non-profit, and I retort with something clever like "And how do you developers feed themselves". •72 ₴ 29

bill this is the kind of mansplaining audacity that’s preserved in museums for future generations to learn from as a cautionary tale

this is mansplaining in the form of a long-term nuclear waste warning message

On Svalbard for #ArcticCrypt2025 - looking forward to a week of daylight, cryptography research and exploration.

Slides of my talk titled "Lattices give us KEMs and FHE, but where are the efficient lattice PETs? -- By Example of (Verifiable) Oblivious PRFs" given at spiqe-workshop.github.io are here: github.com/malb/talks/b...

Thanks @kennyog.bsky.social and @jurajsomorovsky.bsky.social for inviting me.

Reminder that the MSCA postdoctoral program exists. If you have a PhD and want to work in a European lab, you have until September to apply. Just contact them now.

Thanks. I agree with you about the technical analysis. But the question is: how much should one expect from a free, open source project? Same issues arise around time of Heartbleed. Lots of orgs who had never funded OpenSSL had a lot of negative things to say…

This blog from HAProxy is pretty brutal about OpenSSL performance and broader management of the OpenSSL project. But then I have to wonder how much funding HAproxy has contributed to OpenSSL over the years?

Thanks to our wonderful organization team and to the over 800 participants (including the affiliated events) that helped making Eurocrypt 2025 a success!

And now I'll go to sleep for a year or two...

The Signal Clone the Trump Admin Uses Was Hacked TeleMessage, a company that makes a modified version of Signal that archives messages for government agencies, was hacked.

TeleMessage, the Israeli company that makes the modified Signal app used by Trump officials, was hacked. “I would say the whole process took about 15-20 minutes,” the hacker said micahflee.com/the-signal-c...

I always tell this to my research assistants: if you use AI to summarize and write for you, you don't need to be my assistant. You don't need to do research at all.

Research should be selfish: *you* (not a machine) learn how to read, write, innovate, and dream. Otherwise, what is the point?

Is the backend system remotely accessible using the hardcoded credentials? I’d consider that “game, set and match”.

Here's the source code for the unofficial Signal app used by Trump officials Yesterday, I published an analysis of what I could publicly find about TM SGNL, the obscure and unofficial Signal app used by Mike Waltz, and presumably also by Pete Hegseth, JD Vance, Tulsi Gabbard, ...

The source code for the TM SGNL apps (basically a backdoored version of Signal used by Trump officials) is public! Since it's open source, I've pushed it to github for easier research micahflee.com/heres-the-so...

Don't forget to submit your most hilarious talk, musical performance, general announcement or recent result to the Eurocrypt 2025 Rump Session!
