This paper introduces a new way to represent finite posets as subwords of finite words in categories, and characterizes the monic categories that admit this representation.
This paper shows that finite unions of intersecting affine modules in one dimension are efficiently exactly learnable using equivalence and subset queries.
This paper constructs and proves the security of 3-pass Authenticated Key Exchange (AKE) protocols for both KA-based and KEM-based primitives within the commitment-based model, improving upon previous…
SS-ZKR is a novel, three-mechanism protocol that enables privacy-preserving, content-based semantic routing of agent payloads across organizational trust boundaries without requiring the intermediary…

The paper introduces Sherpa.ai, a multi-party Private Set Union (PSU) protocol that enables privacy-preserving entity alignment for Vertical Federated Learning (VFL) without disclosing shared sample i…
This paper compares two cryptocurrency sender untraceability designs, Linear Untraceable Asset Transfer Objects (LUAT) and Constant-State Untraceable Asset Transfer Objects (CUAT), and analyzes their…
KYA introduces a framework-agnostic trust and governance layer for autonomous systems that ensures actions are authorized, policy-conforming, and verifiable through a combination of novel primitives.
The paper proposes FERMI, a method that significantly improves membership inference attacks against tabular diffusion models by leveraging auxiliary relational information available during training, e…

The paper proposes a novel CRT-based asymptotically perfect Disjunctive Hierarchical Secret Sharing (DHSS) scheme that overcomes security and information rate limitations of existing methods.
The paper introduces 'bridges,' a type of morphism between encryption schemes, and provides a general recipe for constructing them, showing that their security relies on the security of the initial sc…
The paper analyzes the structured CVP distance on the log-unit lattice of cyclotomic fields, significantly reducing the conjectured CDPR factor for the ML-KEM cryptosystem from exponential to sub-poly…
This paper introduces Hema, a formally-verified protocol for mutual attestation of Trusted Application (TA) instances running on the same or different Trusted Execution Environments (TEEs).
This paper presents a cryptanalytic attack demonstrating that a specific code-based Private Information Retrieval (PIR) scheme can be broken, allowing the server to efficiently determine the requested…
The paper proposes and evaluates a novel embedding model for bidirectional function association between source code and decompiled/stripped code, significantly outperforming existing models.
The paper introduces SuperPaymaster, an Asset-Oriented Abstraction (AOA) paymaster that eliminates the need for a centralized off-chain signer, thereby improving the decentralization and efficiency of…
This paper studies ranking and aggregation under Kendall tau distance with matroid or flag matroid constraints on prefixes.
The paper shows that the envy-free cake-cutting problem with three agents is intractable and establishes the first lower bounds for the Jordan curve problem.
