Chu-ko-nu: A Reliable, Efficient, and Anonymously Authentication-Enabled Realization for Multi-Round Secure Aggregation in Federated Learning
Secure aggregation enables federated learning (FL) to perform collaborative training of clients from local gradient updates without exposing raw data. However, existing secure aggregation schemes inevitably perform an expensive fresh setup per round because each client needs to establish fresh input-independent secrets over different rounds. The latest research, Flamingo (S&P 2023), designed a share-transfer-based reusable secret key to support the server continuously performing multiple rounds…

Generic low-atmosphere signatures of swirled-anemone jets
Solar jets are collimated plasma flows moving along magnetic field lines and accelerated at low altitude following magnetic reconnection. Several of them originate from anemone-shaped low-lying arcades and the most impulsive ones tend to be relatively wider and display untwisting motions. We aim to establish typical behaviours and observational signatures in the low atmosphere that can occur in response to the coronal development of such impulsive jets. We analysed an observed solar jet associa…

Lehrevaluation. Im Kurs sind 17 Frauen und 1 Mann. Bzw. 17 weiblich gelesene Personen und eine männlich gelesene Person, wie man heutzutage sagt. Bei der Lehrevaluation wurde das Geschlecht abgefragt w/m/d. Das Ergebnis war: 17 weiblich, 1 keine Angabe. Da dachte sich wohl jemand, wenn ich männlich ankreuze, dann bin ich nicht mehr anonym.
Der richtige Weg dafür wäre wohl gewesen, weiblich anzukreuzen.
Aber da ich die Fragebögen eh nicht zu Gesicht bekomme (war online), ist alles prima.

An Extended View on Measuring Tor AS-level Adversaries
Tor provides anonymity to millions of users around the globe which has made it a valuable target for malicious actors. As a low-latency anonymity system, it is vulnerable to traffic correlation attacks from strong passive adversaries such as large autonomous systems (ASes). In preliminary work, we have developed a measurement approach utilizing the RIPE Atlas framework -- a network of more than 11,000 probes worldwide -- to infer the risk of deanonymization for IPv4 clients in Germany and the U…
