I-(OT)^2: A Client-optimal Oblivious Transfer Protocol for IoT Devices
Elia Onofri, Andrea Ciccotelli, Roberto Di Pietro
Oblivious Transfer (OT) is a fundamental cryptographic primitive enabling privacy-preserving computation and constitutes a core building block for secure multi-party computation wh…
A Geometric Analysis of Small-sized Language Model Hallucinations
Emanuele Ricco, Elia Onofri, Lorenzo Cima +2
Hallucinations -- plausible but factually incorrect responses -- pose a major challenge to the reliability of Large Language Models (LLMs), especially in multi-step or agentic sett…
COD-ssi: Enforcing Mutual Privacy for Credential Oblivious Disclosure in Self Sovereign Identity
Elia Onofri, Andrea De Salve, Paolo Mori +2
The Self-Sovereign Identity (SSI) paradigm is instrumental for decentralised identity management, allowing an entity to create, manage, and present their digital credentials withou…
Bayesian methods for the identification of model parameters for water transport in porous media
Paola Stolfi, Elia Onofri, Gabriella Bretti
The structure of the nonlinear inverse problem arising from capillarity-driven imbibition in porous media is investigated, considering a degenerate parabolic PDE with compactly sup…
On -Contraction and -Contraction: A Unified Framework for Colour-Preserving Graph Reduction
Elia Onofri
Graphs are a fundamental abstraction in computer science and discrete mathematics, where information is encoded in their combinatorial structure. Graph-reduction techniques aim at…
Structural Identifiability and Comparative Calibration of Water Retention Curves for Imbibition in Porous Media
Gabriella Bretti, Maurizio Ceseri, Elia Onofri +1
This paper investigates the structural identifiability and a comparative calibration of four water retention curves (WRCs) within the framework of the Richards equation coupled wit…
