“BlockTrail: A Service for Secure and Transparent Blockchain-Driven Audit Trails” by Ashar Ahmad, Muhammad Saad, Mohammed Al Ghamdi, DaeHun Nyang, David Mohaisen is accepted in IEEE Systems Journal. Congratulations to all!
In this paper, we introduce BlockTrail, a novel blockchain architecture that is prototyped on the PBFT protocol with a custom-built blockchain. BlockTrail is secure and efficient, while having low storage footprint.



Me, waiting for the award in NetSec-KR 2021 after keynote speech.



The work is on studying the impact on children by inappropriate comments in YouTube, and it is now accepted for publication in SocialNLP 2021.
Last year was awesome. Our group had published successfully fair amount of papers in top venues like INFOCOM, ICDCS, PETS, IEEE IoT Journal, IEEE TC, etc. Still we are working on many exciting topics on streaming algorithms on a programmable router, AI attack, AI-powered network security, and more. The progress is rather slow, but the collaboration network among Prof. Mohaisen, Prof. Jang, and Prof. Abuhamad are settling down and so more amazing outcomes will be seen soon. Another important mission is to raise students at Ewha, a new home in Seoul. Four undergraduate interns will be joining us this month, and hope that they grow academically here in my lab. Welcome, Yuyeon, Sumin, Bomin, Yujin!
