Kichang Yang at Hyundai motor company gave a talk on vehicular security in cyber security department’s weekly colloquium at Ewha. His talk showed many interesting vehicular security issues as well as what to do to become a vehicular security engineer. It must be very helpful to young students as a career guidance. He has been leading a security group as a director of security division in HMC since 2016. His group is working on all aspects of vehicular security like hacking, reproducing reported vulnerabilities, regulations, and what not. We got to understand what are the issues in vehicular security, career path, and even how to do a good interview.

Every week, we will have an invited talk about various issues in security!

Now, we are BRL (Basic Research Lab) together with Prof. Dongbo Min and Prof. Se Eun Oh.

  • Title: Research on SPV(Security/Privacy/Visual) Firewall for Connected Autonomous Vehicle
  • Period: 2023.6-2026.2
  • Budget: 1.375 billion KRW
  • Aim: In recent years, the amount of data exchanged between automobiles and external networks has increased exponentially due to big data, deep learning, and connectivity to various network services such as IoT and cloud. Therefore, attacks on the network can have a significant impact on the security and privacy of the car, and in response, academia and industry are focusing on automotive security. In addition, artificial intelligence attacks on autonomous driving technology, which is a major trend in automobiles, are also emerging, but there is still no research on autonomous driving technology that detects hostile attacks in real time. Therefore, research on network security, privacy protection, and visual attack prevention firewalls for autonomous vehicles that can quickly detect and defend against attacks in real time while the vehicle is in operation is very important.

 

 

  • Funding source: National Research Foundation
  • Program: Mid-Career Researcher Program Type 1-2
  • Period: 2023.3.1-2028.2.29
  • Budget: One billion KRW for five years

Research statement: From a network security perspective, one of the most important recent trends is “In-Network Defense”. In addition to endpoint security and perimeter security, which have been the focus to date, there is a new trend of enabling security functions in the backbone network. Moving away from the current perspective that defines the role of the network as performing only routing functions, the network is being asked to perform more advanced functions from a security perspective, which essentially foreshadows the emergence of routers equipped with artificial intelligence models. Along with the rapid development of deep learning in most fields of IT and the growing importance of data analysis using AI/ML technologies, various attempts have been made to enable routers with AI models to analyze network traffic on a per-flow basis to perform security functions. However, performing AI models within the router without delaying the delivery of large numbers of high-speed packets is not feasible by current technologies. Therefore, it is our goal to develop a self-driving router that performs AI models in real time and autonomously performs security-related functions.

Another big news. Our paper titled “A Robust Counting Sketch for Data Plane Intrusion Detection”, proposing Count-Less, is accepted in NDSS 2023! This paper is part of the series of works that our group has been pursuing on data sketch for traffic measurement and security applications. Count-Less is a major variation of the famous Count-Min sketch, but is more robust in terms of measurement accuracy under a various traffic distributions, including attack traffic. The design of the sketch is lightweight enough to fit in the packet processing pipeline and sketch’s performance is shown to be superior to state-of-the-art algorithms, such as Elastic sketch and FCM by comprehensive experiments.

 

Congratulations to Sian, Changhun, Rhongho, David, and me!

I am pleased to share that our paper “A Scalable and Dynamic ACL System for In-Network Defense” (named PortCatcher) is accepted in CCS 2022! A big achievement of our research group.

Summary by David: This work addresses the scalability of dynamic ACL systems through an elegant combination of algorithmic optimization and new architectural design that exploits SRAM instead of TCAM for ACL storage. The work is implemented in P4 and this coupling allows us to process packets at the line speed, even for orders of magnitude growth in size of the ACL in contrast to TCAM-based approach.

Congratulations to Changhun Jung, Sian Kim, Rhongho Jang, David Mohaisen, and Me.

More news will come soon. 😉
