About Me
I am pursing my PhD degree at the Department of Computer Science,
Purdue University since 2009 fall. My advisor is Prof. Charles
Killian.
Before I join Purdue, I received the BS and MS degree in
computer engineering from Hongik University, Korea, and my
advisor was Prof.
Sam H. Noh.
Research
My research interest includes various topics in distributed
systems and operating systems. Currently, I am trying to
automatically find attacks from distribute systems
implementations. To date, finding attacks against performance
has been primarily a manual task due to both the difficulty of
expressing performance as an invariant in the system and the
state-space explosion that occurs as attackers are more
realistically modeled. Our goal is to find performance
attacks automatically requiring the least amount of user
effort.
