The Crypto Forum Research Group (CFRG, part of the @inretafo), is holding a last call for two documents on hybrid KEMs: a mechanism that lets you safely combine post-quantum and classical algorithms into a single construction. mailarchive.ietf.org/arch/msg/cfrg/…

@sweis Can you explain what you mean here?

The funniest part of the TLS WG non-hybrid ML-KEM drama is that Classical McEliece was simultaneously being pushed as a non-hybrid ISO standard: #iso:std:iso-iec:18033:-2:ed-1:v1:amd:2:v1:en" target="_blank" rel="nofollow noopener">iso.org/obp/ui/en/#iso…

Özgür Kesim gave a talk about the digital euro at 3F. He takes a critical look at the design of the digital euro based on the paper "Digital Euro: FAQ Questions Revisited" (arxiv.org/pdf/2601.18644). The slides from the talk are at concretecontracts.codeblau.de/talks/3f-2026.…

I've been involved with ISO/IEC JTC1 SC27 WG2 discussions about Simon/Speck, Kuznyechik, and QKD (and some more). This is nothing in comparison to the IETF TLS mailing list.

Somewhat behind schedule, but the Classic McEliece standard is finally out. tue.nl/en/news-and-ev…

Links to all videos on YouTube are up at eipsi.win.tue.nl/surveillance.h… and we're adding slides as we get them

One interesting aspect of web.archive.org/web/2026062222… is the demand that federal contractors (starting mid-2027) label "the use of non-FIPS approved algorithms" as a "vulnerability". The 1990s version of this would be telling contractors to label RSA above 512 as a "vulnerability".

Update on "Security in Times of Surveillance" We understand that some of you cannot attend because of the heat .Our expectation is that TU/e will be open and the AC will be on. We try to stream the talks on YouTube youtube.com/channel/UC_x5V… Program etc eipsi.win.tue.nl/surveillance.h…

Almost all talk titles are online now. Please register before Friday so that we can order catering eipsi.win.tue.nl/surveillance.h…

The EU has a survey open on the QKD network EuroQCI, asking how they should invest their money. I've sent them some idea. (hint: replace by PQC). You can also still contribute your input. Not sure how much longer this will stay up: ec.europa.eu/eusurvey/runne…

@TUe_MCS We've now posted the schedule for the event. Come for a day of insightful and engaging talks. eipsi.win.tue.nl/surveillance.h…

Registration is open for our next Security in Times of Surveillance event taking place 26 June at @TUe_MCS eipsi.win.tue.nl/surveillance.h… Speakers include Martin Albrecht, Chloe Berthelemy, Rikke Bjerg Jensen, Thomas Lohninger, Bjoern Ruytenbert, and Carmela Troncoso

Bit of a last-minute announcement: school on isogenies 9 - 13 Feb at Okinawa Institute of Science and Technology (OIST) groups.oist.jp/tsvp/event/sch… Registration deadline is tomorrow (15 Jan).

Our project doesn't have an account here, so I'm crossposting bsky.app/profile/pqcsa.… Most interesting IMO is D1.3 Hot topics & open problems in PQC . Link to drafts and disclaimers pqcsa.eu/deliverables.h…

Deadlines for PQCrypto2026 are around the corner! Papers must be _registered_ by 31 Oct pqcrypto2026.irisa.fr/callforpapers.… You can still update your submission for another week, with the final submission deadline on 7 Nov. You cannot register new papers during that period. Get yours in now!

For people in Germany there is also the low-effort option of signing a petiton if you want to take action against chat control weact.campact.de/petitions/chat… Running since yesterday and already at more than 200k signatures.

If you're good at talking to politicians, contact your representatives, in particular in countries still undecided. Many don't understand the risks and implications and fall for the emotional arguments. I appreciate the attitude but this exposes us to hacking & mass surveillance

Our "Joint statement of scientists and researchers on the EU Presidency’s new proposal for the Child Sexual Abuse Regulation" has reached more than 700 signatures. If you're scientist, consider co-singing. Proposal would be a security nightmare, but many states consider approval

My colleague, Lorenzo Grassi, has another PhD position open. tue.nl/en/working-at-… Deadline stated is 12 Oct but the position will close as soon as a candidate is found. Starting date no sooner than Mar 2026. Applications must be received via the TU/e page.

The next two editions of the Crypto Working Group will be on 5 Sep (next Fri) and 28 Nov. Details to come soon at eipsi.win.tue.nl/seminars_cwg.h… Location is as always the Kargadoor in Utrecht.
