Model-Free Generative Stealthy Attacks on Safety-Critical Vehicle Cyber-Physical Systems
Qazi Mairaj ud din, Sidra Ghayour Bhatti, Qadeer Ahmed
Existing stealthy attacks presuppose white- or grey-box access to the target system, unrealistic in practice. This paper develops a model-free stealthy attack framework that learns…
When Stealth Requires Memory: Budgeted Attack Scheduling under a Whiteness Constraint
Qazi Mairaj ud din, Sidra Ghayour Bhatti, Qadeer Ahmed
We pose stealthy attack scheduling on a sensor-to-estimator link under a resource constraint with a budget \barΓ on the fraction of corrupted transmissions and a model-free whitene…
Distribution-Free Budgeted Stealthy Attack Scheduling for Remote State Estimation
Qazi Mairaj ud din, Sidra Ghayour Bhatti, Qadeer Ahmed
This letter addresses budgeted stealthy false-data-injection (FDI) scheduling against remote state estimation, where a resource-constrained adversary may corrupt at most a fraction…
Ranking-Augmented On-Policy Optimization with Adaptive Advantage-Normalization for Constrained Control
Md Ragib Rownak, Sidra Ghayour Bhatti, Qadeer Ahmed
This paper analyzes the boundedness and feasibility properties of Advantage-Ranked Group Relative Policy Optimization (A-GRPO), a ranking-augmented, critic-free policy gradient met…
Model-Free Budgeted Attack Scheduling for Cyber-Physical Systems
Qazi Mairaj ud din, Sidra Ghayour Bhatti, Qadeer Ahmed
This letter studies the budgeted scheduling of stealthy false data-injection (FDI) attacks against state estimators in cyber-physical systems. Existing event-based attack scheduler…
Sequence Aware SAC Control for Engine Fuel Consumption Optimization in Electrified Powertrain
Wafeeq Jaleel, Md Ragib Rownak, Athar Hanif +2
As hybrid electric vehicles (HEVs) gain traction in heavy-duty trucks, adaptive and efficient energy management is critical for reducing fuel consumption while maintaining battery…
Multi-Stage Knowledge-Distilled VGAE and GAT for Robust Controller-Area-Network Intrusion Detection
Robert Frenken, Sidra Ghayour Bhatti, Hanqin Zhang +1
The Controller Area Network (CAN) protocol is a standard for in-vehicle communication but remains susceptible to cyber-attacks due to its lack of built-in security. This paper pres…
Improving Q-Learning for Real-World Control: A Case Study in Series Hybrid Agricultural Tractors
Hend Abououf, Sidra Ghayour Bhatti, Qadeer Ahmed
The variable and unpredictable load demands in hybrid agricultural tractors make it difficult to design optimal rule-based energy management strategies, motivating the use of adapt…
KD-GAT: Combining Knowledge Distillation and Graph Attention Transformer for a Controller Area Network Intrusion Detection System
Robert Frenken, Sidra Ghayour Bhatti, Hanqin Zhang +1
The Controller Area Network (CAN) protocol is widely adopted for in-vehicle communication but lacks inherent security mechanisms, making it vulnerable to cyberattacks. This paper i…
