Professor Nam Seung-yeop of Yeungnam University Receives Best Paper Award from Prestigious International Journal

Professor Nam Seung-yeop of the Department of Information and Communication Engineering at Yeungnam University received the 2022 Best Paper Award from the internationally renowned journal Digital Communications and Networks (impact factor (IF) 6.438).

The paper presented by Professor Nam is titled "A new type of blockchain for secure message exchange in VANET (Vehicular Ad-hoc NETwork, a type of vehicle communication network)." It is a research achievement on a new blockchain structure that can securely share the reliability of messages exchanged within the vehicle communication network.

Professor Nam stated, “In this study, we minimized the possibility of falsehood regarding the trustworthiness of oneself or other nodes (network connection points) by utilizing the immutability characteristic of blockchain. Additionally, we confirmed that it is possible to stably manage the trustworthiness of vehicles and the messages exchanged between vehicles while overcoming the problem of trust inconsistency per node inherent in existing distributed trust-sharing methods.”

As the era of autonomous vehicles approaches, the trustworthiness of messages exchanged between vehicles and the trustworthiness of the vehicles transmitting those messages are expected to become increasingly important. As of February 2023, Professor Nam’s paper has attracted significant attention in academia and industry, being cited over 200 times according to Google Scholar.

This research was conducted with Dr. Rakesh Shrestha, who earned his Ph.D. in Professor Nam’s lab and worked as a postdoctoral researcher, as the first author, and Professor Nam as the corresponding author.

Dr. Rakesh is currently conducting research in the field of IoT Security at the RISE Research Institute in Sweden, while Professor Nam is carrying out research on "Blockchain Applications in Vehicle Networks" (Mid-career Researcher Support Project) and "Future Mobility Ultra-Safety Research" (University Focused Research Center Support Project) supported by the National Research Foundation of Korea.
