New paper, joint with Jeroen Pijnenburg (RHUL), is up on ePrint and will appear at SAC later this month: eprint.iacr.org/2022/1017 This work was motivated by the question, "what key should I use to encrypt my Instant Messaging backups?" (short 🧵)

@drl3c7er @gareth_t_davies @tiborja Thank you! Happy you liked it :)

Denis Diemert (@de_diem) from BUW presenting the cool paper on tight security of TLS 1.3 PSK at Eurocrypt 2022, joint work with Hannah Davis, Felix Günther and @tiborja ia.cr/2022/246 #eurocrypt2022

Our EUROCRYPT '22 paper with Hannah Davis, @de_diem, and Felix Günther is now on ePrint: eprint.iacr.org/2022/246

If scientists from Ukraine want to apply here, but need advice e.g. due to a lack of familiarity with the German academic system or anything else, please contact me, I am happy to help.

Here is our paper on memory-tightly secure digital signature schemes, to appear at ASIACRYPT 2021. Inofficial title: "Another Look at the Impossibility of Memory-Tightly Secure Signatures". eprint.iacr.org/2021/1220

#ePrint Cryptimeleon: A Library for Fast Prototyping of Privacy-Preserving Cryptographic Schemes: J Bobolz, F Eidens, R Heitjohann, J Fell ia.cr/2021/961

You want to know how fast prototyping of privacy-preserving cryptography is possible? Then jump right into the 5 minute tutorial of Cryptimeleon (cryptimeleon.org/getting-starte…) or read the paper (ia.cr/2021/961). It is an open-source Java library aimed at #crypto researchers.

Looking forward to give a quick five-minute presentation about this at #PKC2021 in about an hour (pkc.iacr.org/2021/program.p…)

Four times "It is a pleasure to inform you..." at #PKC2021 for our crypto group at @Uni_Wuppertal (one conditionally). Congratulations to all successful authors!

Our online course foundations of cryptography was picked as a leading example of how good online teaching at Paderborn University works. Thanks to all students for the support We published 56 tutorial videos and provided a discourse forum for anonymous Q&A bit.ly/3jS4KWh

Includes our work on fast and secure updatable encryption eprint.iacr.org/2019/1457

@tibor_jager I try to do my very best! 😀

If you are interested in this line of work, consider following @de_diem, too, and stay tuned for more results coming up! (He might even make less typos in his tweets than I do.)

Da ich wegen @aminlaschet bei @annewill wieder nicht schlafen konnte, hier nochmal für A-L-L-E: Wir haben eine sehr effektive Nicht-pharmakologische-Intervention (NPI) gegen SARS-CoV2. Diese NPI heißt Einzelfallverfolgung (#testtraceisolate) - BITTE WEITERLESEN 1/9 #COVID19

#ITSicherheit wird für kleine u. mittlere #Unternehmen immer wichtiger. Doch oft fehlt Fachpersonal. In einem neuen @BMWi_Bund geförderten Forschungsprojekt entwickeln Wissenschaftler der Uni Paderborn passende u. kosteneffiziente Weiterbildungsangebote: go.upb.de/KMUEinfachSich…

My new workplace! Visit us in Wuppertal and let's see if we can fit an entire paper on the whiteboard ✏️
