A Loss-Robust Disturbance Certificate for Minimal-Receiver Quantum Key Distribution
Roberto Di Pietro
Quantum Key Distribution (QKD) enjoys information-theoretic security, yet the most damaging attacks against deployed systems exploit the receiver, where the key bit is encoded in w…
TENET: Telegram Mini App (in)security
Andrea Ciccotelli, Federico Zappone, Roberto Di Pietro
Telegram, with over 450 million daily active users, has introduced Mini Apps---web-based applications running directly within its client. However, this integration introduces notab…
Self-State Attacks on Self-Hosted AI Agents: How Far Can OS Defenses Go?
Yimeng Chen, Nathanaël Denis, Roberto Di Pietro +1
Self-hosted AI agents maintain persistent memory, instructions, and configuration that influence their future behavior. If an agent is compromised, an attacker can exploit the agen…
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…
Characterizing Polkadot's Transactions Ecosystem: methodology, tools, and insights
Maurantonio Caprolu, Roberto Di Pietro, Flavio Lombardi +1
The growth potential of a crypto(currency) project can be measured by the use cases spurred by the underlying technology. However, these projects are usually distributed, with a we…
Analysis of Polkadot: Architecture, Internals, and Contradictions
