Thank you Dr. Vera Rimmer for the deep dive into your PhD project "Applied Deep Learning in Security and Privacy". Congratulations!

163 reviews since 2020... it's healthy to practice your "No" from time to time 🤪

The prototype of VerLoc is available on GitHub https://t.co/GZOzHrWYho and currently under development to be integrated into real-world systems.

[Katharina Kohls @blister_green]

Yay! Our paper "VerLoc: Verifiable Localization in Decentralized Systems" got accepted at @USENIXSecurity 22! This was a super fun project together with @claudsdayz and with the support of @nymproject

@USENIXSecurity @claudsdayz @nymproject VerLoc helps to verify the locations of nodes in a decentralized system. It uses timing probes to estimate a node's location and is robust to up to 20% malicious nodes in the network.

It is our pleasure to announce that we organizing Alice &Eve 2021 https://t.co/mGSKnjyy9k to celebrate #women in #computerscience Register here and join us!

[Katharina Kohls @blister_green]

@MarkusMonka Oh, thanks for the reminder! Both machines have "5g" set as the pw. I have added this to the website as well.

Setting up a 2-VM Open5GS network with UERANSIM: There are some great tutorials out there, but none really covers all the parts I needed. So I've put up a full guide here https://t.co/9zcJqjp1F7

Zur weiteren Unterstützung und aufbauend auf den 2G Vorarbeiten von Osmocom bereitet @srsRANProject einen Blog Post mit Anleitung zum Aufbau eines Demonstrators von Cell Broadcast mit freier Software für 4G/5G Netze auf. Vielleicht bringt uns das ja ein bisschen weiter ..

[Katharina Kohls @blister_green]

@Y0da4a That's definitely possible, just not in this VM setup :) You can still use one of the open 5G core implementations for that, but you would need some other 5G gNB implementation + UE. Maybe have a look at https://t.co/oWPI4AmLsP

[Katharina Kohls @blister_green]

@Y0da4a This is a fully virtual setup. Open5GS runs in VM 1 and UERANSIM takes care of the UE and gNB components in VM 2. Besides the host machine no hardware is needed here!
