Compositional security definitions for higher-order where declassification

Jan Menz, Andrew K. Hirsch, Peixuan Li, Deepak Garg · 2026

To ensure programs do not leak private data, we often want to be able to provide formal guarantees ensuring such data is handled correctly. Often, we cannot keep such data secret entirely; instead pro…

Efficient Fuzzy Private Set Intersection from Secret-shared OPRF

Xinpeng Yang, Meng Hao, Chenkai Weng, Robert H. Deng, Yonggang Wen, Tianwei Zhang · 2026

Private set intersection (PSI) enables a sender holding a set $Q$ of size $m$ and a receiver holding a set $W$ of size $n$ to securely compute the intersection $Q \cap W$. Fuzzy PSI (FPSI) is a PSI va…

"I Just Don't Want My Work Being Fed Into The AI Blender": Queer Artists on Refusing and Resisting Generative AI

Jordan Taylor, Joel Mire, Alicia DeVrio, Maarten Sap, Haiyi Zhu, Sarah E. Fox · 2026

Art-making is a collective social activity through which queer people engage in political resistance, develop identities, archive queer memory, and form community. However, in recent years, generative…

Parallel Algorithms for Group Isomorphism via Code Equivalence

Michael Levet · 2026

In this paper, we exhibit $\textsf{AC}^{3}$ isomorphism tests for coprime extensions $H \ltimes N$ where $H$ is elementary Abelian and $N$ is Abelian; and groups where $\text{Rad}(G) = Z(G)$ is elemen…

Edge-Tilting Field Dynamics: Rapid Mixing at the Uniqueness Threshold and Optimal Mixing for Swendsen-Wang Dynamics

Xiaoyu Chen, Zhe Ju, Tianshun Miao, Yitong Yin, Xinyuan Zhang · 2026

We prove two results on the mixing times of Markov chains for two-spin systems. First, we show that the Glauber dynamics mixes in polynomial time for the Gibbs distributions of antiferromagnetic two-s…

When Majority Fails: Tight Bounds for Correlation Distillation Conjectures

Pritish Kamath, Ravi Kumar, Pasin Manurangsi · 2026

We study two conjectures posed in the analysis of Boolean functions $f : \{-1, 1\}^n \to \{-1, 1\}$, in both of which, the Majority function plays a central role: the "Majority is Least Stable" (Benja…
