What the lab Does

Intrusion Detection Systems and DDoS defense mechanisms in Mobile Networks

Distributed Denial-of-Service (DDoS) attacks and security attacks against zero-day vulnerabilities (e.g., energy depletion attacks, crypto mining) have been the top concerns of the security community and the enterprise for decades. These attacks are causing losses of billions of dollars each year to governments, companies, and mobile users. Preventing these types of attacks is always the top goal of the research community. In this research branch, the host has gained many notable achievements. For example, we have developed advanced unsupervised machine learning models and tunnel-traffic filters to successfully mitigate DDoS attacks and abnormal intrusion activities. The studies are already published in the top journals of the field, e.g., JISA, JNCA, NETWORK. Several of them are highly cited. Typical papers for this branch are summarized as follows.

Misbehavior Detection and Physical Layer Security in Vehicular Networks

Our society is approaching the era of connected and autonomous vehicles. Vehicle-to-Everything (V2X) communications are expected to be increasingly used for improving coverage, particularly in locations where a vehicle's camera or radar is ineffective. However, trusting the sharing data, the control systems in such connected receivers can be trapped to change to a wrong lane or accelerate unexpectedly, and then potentially lead to a crash. In this research branch, we have developed several signal-based misbehavior detection and physical layer security defense methods to enhance the trustworthiness of V2X broadcasting messages, given the presence of falsification/Sybil attacks. We found that the signal-based approach has many advantages. First, the signal source is hard to be faked, so the detection engine can easily detect sophisticated attacks like Sybil attacks. Second, it requires no additional data exchange between vehicles (extract channel information directly from communications) and thus helps to reduce communication overhead. In the last three years, the host also published the studies in the top journals of the field, e.g., S&P, COMST, TVT, and COMML. The impact factor of the IEEE COMST journal is as high as 25.249 in 2021. Typical articles for this branch are as follows.

  1. (S&P) Edy Kristianto, Van-Linh Nguyen, and Po-Ching Lin, “Decentralized PKI with Blockchain in V2X Communications: Promising or only Euphoria?” IEEE Security & Privacy, 2022, [SCI/SCIE] (SJR Journal Impact Factor 2021: 3.573, Rank 94/334, Q1, in Computer Science).

(High cited)

Physical layer security

Mobile networks have become one of the vital factors in our life. However, the appearance of Wireless Everywhere potentially poses surveillance risks to mobile users, particularly being tracked illegally. Physical layer security is then another core research of the lab. In this research direction, we exploit the power of AI to design robust anti-tracking/anti-jamming systems that can survive better against sophisticated attack strategies than the current approaches can do.

Intelligent Traffic Coordination for Connected and Autonomous Vehicles

Besides security matters, the host has also published several research papers about traffic scheduling and transmission control for connected and autonomous vehicles. For example, the T-ITS paper presents an efficient path planning and traffic clear-out scheduling scheme to lessen the emergency vehicles (EVs)' travel time by estimating a list of candidate paths to the rescue spot with the estimated time of arrival at the EVs' maximum speed, regardless of the traffic conditions. After that, a vehicle clear-out process evaluates the delay time of clearing out the traffic obstacles on each path to identify the fastest driving path. Finally, the system estimates and issues the signal preemption schedules for the junctions of the selected route to coordinate the traffic flows and let the EV pass through smoothly. This approach can outperform the state-of-the-art solutions in terms of the EV's travel time reduction, particularly if the congestion appears on the selected route but is far from the departure location of the EV. The typical papers in this branch include:
