Summary

• What is new: Proof-of-concept attack on STVs using a malicious HbbTV app and automated, low-cost methods for CCPR determination and non-disruptive attack range measurements.
• Why this is important: The DVB standard’s lack of mandated authentication and integrity for transport streams, allowing malicious broadcasts to exploit STVs.
• What the research proposes: Developed methods for detecting and measuring the limitations of these attacks based on CCPRs, including a malicious app attack proof-of-concept.
• Results: Evidence of the attacks’ limited range through lab experiments, simulations, and field measurements, contradicting previous publications.

Technical Details

Technological frameworks used: Automated, low-cost CCPR determination and attack range measurement using gap fillers and channel impulse response analysis.

Models used: Hybrid Broadcast Broadband TV (HbbTV) app for system-level access to STVs.

Data used: Laboratory experiments, extensive simulations, and field measurements.

Potential Impact

Smart TV manufacturers, broadcast companies, and digital security solutions could be affected or could benefit from these findings.
