Hybrid Hierarchical Runtime Verification for Edge-IoT Security: Combining MonPoly and RTLola
Nikolaos Kekatos, Marinelio Chintri, Panagiotis Katsaros +5
Security monitoring of edge-IoT fleets faces three structural challenges. (i) A per-node monitor is cheap but cannot see attacks that coordinate across devices. (ii) A cloud monito…
Formal Runtime Verification for Tool-Using LLM Agents: An Offline Same-Benchmark Study on AgentDojo and STAC
Nikolaos Kekatos, Stylianos Basagiannis, Marinelio Chintri +5
Guardrails for tool-using LLM agents are usually application-specific rules, which makes multi-step, data-dependent safety policies hard to specify, audit and reuse. As a declarati…
Multi-Aspect Runtime Verification for Simulation-Based V&V of LLM-Enabled Autonomous Agents
Nikolaos Kekatos, Dimitrios Nikou, Anastasios Temperekidis +4
LLM-based agents are entering decision-support roles in defence staff work, where the obligations they must respect are already written down and binding, and where retraining is no…
A Resilient Runtime-Verification Fabric for Security Monitoring of Critical Edge-IoT Infrastructure
Nikolaos Kekatos, Marinelio Chintri, Panagiotis Katsaros +5
Protecting critical infrastructure increasingly depends on continuously verifying large IoT fleets against formal security specifications at runtime. Yet the runtime-verification (…
A Digital Twin prototype for traffic sign recognition of a learning-enabled autonomous vehicle
Mohamed AbdElSalam, Loai Ali, Saddek Bensalem +6
In this paper, we present a novel digital twin prototype for a learning-enabled self-driving vehicle. The primary objective of this digital twin is to perform traffic sign recognit…
