VEC-SecOffload: A Hardware Testbed Dataset for Secure Task Offloading in Vehicular Edge Computing under DoS Attack Conditions

This dataset contains results from a 200-trial hardware testbed evaluation of a multi-layer security framework for VEC task offloading, covering four scenarios across benign and DoS-hostile conditions. Metrics include task success rate, latency, energy consumption, and IDS alerts, collected from 8 RSU edge servers and 40 vehicle OBUs across a 2000 m × 2000 m urban grid. The dataset supports reproducibility of the reported findings and benchmarking of future secure VEC offloading frameworks.
