Jobber med Tjerand på ZKP. 2. **Lotta**, PhD at IMF med Kristian, jobber med EasyCrypt. Huh, forskningsvisitt i Bristol fra september. 3. **Danilo**, professor ofc., har designet hashfunksjoner og sånt tidligere. Invitert til en workshop av Kerchack-team? Will pose challenge for upcoming 6G, "scrambling", it's not encryption. En slags permutasjon. So challenge: gitt at scrambling allerede foregår, kan kryptografer gjøre noe i denne delen av stacken som kan faktisk gi sikkerhetsgarantier? Og så public key exchange with LLMs ... ? Skjønner ikke. "But just to entertain myself with LLMs." Underviser også Advanced Ethical Hacking. 4. **Tikkaram**, postdoc. Jobber med FHE, submittet nylig to papers. Jobber med Tjerand, Emil and Ana on bootstrapping. Noe med at de hadde et angrep som involverte LLM tidligere, men så fant de ut at de bare trengte "a simple linear model"? 5. **Kristian**, professor, IMF, gjør key exchange, voting, identification, "I try to keep up with the easycrypt people". Underviser kryptokurs ved IMF. 6. **Caroline**, jobber med Tjerand og Patrick på DKE for NTRU, samt de samme pluss Katz på et lattice-based threshold scheme. TA for Tjerands kurs og Bors kurs. Skal også på Sikkerhetsfestivalen, presenterer om det nye masterprogrammet for kryptografi ved NTNU. Skal også på ZK-workshop i Edinburgh, "which I'm really excited about, because it will be the first time I meet my co-authors". Har også et paper in submission om lattice-based e-voting (? les?). 7. (Pronounced) **Chang-jun**. Been working on FHE, but tired of the topic so wants to switch. Looking at transformations from CPA secure PKE to CCA secure PKE in the standard model (!). Teaching Blockchain and cryptocurrency this semester. 8. **Lea**. 4th year phd student. Main focus is working on three re-submissions. Working on circuit security for BGE(?), og IND-CPAD security for approx. homomorphic encryption, samt PIR fra FHE. Jobber med Tjerand, Ana, Mattia. Also interested in a unified framework for noise analysis across various FHE schemes. Also on a project in private set intersection. Some teaching (assistant?). 9. **Chris**: Jobber med Tropical Crypto (?). Currently: How some lattice problems relate to this new environment. Recently started collab with Sergei Fehr (!). Tropical Crypto simplifies the usual arithmetic, semi-rings, addition is just maximum of two elements, and multiplication becomes addition. Gives new interesting results and connections and possibilities. Recent development; papers mostly from 2020 onwards. 10. **Meg** 11. **Sonu**. PhD student (but not candidate?), working with Tjerand on an MLWE protocol, now working on implementation. 12. **Tjerand**. Most research projects already mentioned by others. Teaching Secure Cryptographic Implementations. 45 signed up for room capacity of 37. On board of CiC. Organizing ZK workshop, 65 attendees. NKS in Gjøvik. Two big applications on behalf of the department. If the first one goes through, that is between NOK 50-100M over 8 years. Also application for research schools, resurrect COINS, submission deadline in november. General chair of PKC together with Bor. Looking for sponsors. Have applied for sabattical in the spring, but decision is postponed. If approved, will be gone half the semester (det var ikke mye!). 13. **Emil**. Some projects. Some TAing. That's it. 14. **Oskar**, PhD student. Easycrypt applied to hybrid PQ protocols. Stretching the capabilities of Easycrypt, which is not really made for protocols. Might lead to some interesting developments of Easycrypt actually, is in contact with their developers. 15. **Staal** (remote), professor i Gjøvik (men bor i Oslo og pendler dit kun når han underviser, én gang i uken). Differential privacy etc. Parental leave 2nd half of semester. Teaching "usual course" in fall. 16. **Jonathan**, (remote from train). Working on preparing for PhD defence next Friday. Isogeny-based stuff. Vanskelig å høre ham, dårlig connection. Next week Scott will hold a talk. ### To-do denne uken Husk, ta én ting av gangen.
