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!
