Exploiting Multicore Architecture for Secure, Revivable Services

Cyber exploits and remote attacks on network servers have become enormous concerns by service providers, online merchants and Internet users. In this talk, I will present a high-availability system architecture based on emerging multicore (or CMP) processors. This architecture named INDRA --- Integrated framework for Dependable and Revivable Architecture enhances a multicore processor with novel security and fault recovery mechanisms to combat malicious, remote exploits. By exploring the properties of a tightly-coupled multicore system, INDRA creates a hardware insulation, establishes fine-grained fault monitoring, exploits monitoring/backup concurrency, and facilitates fast recovery services with minimal performance impact. In addition, INDRA's fault/exploit monitoring is implemented in the software rather than in the hardware logic, thereby providing better flexibility and upgradeability. To provide efficient service recovery and thus improve service availability, I will present a novel delta state backup and recovery on-demand mechanism that outperforms conventional check pointing schemes. I will also discuss our on-going experimental environment development based on Bochs and some performance results in this talk.

Hsien-Hsin Lee is an assistant professor of the School of Electrical and Computer Engineering at Georgia Institute of Technology. Hsien-Hsin "Sean" Lee received his PhD degree in computer science and engineering from the University of Michigan at Ann Arbor. His research interests include computer architecture, low power circuits, information security, and 3D ICs. Prior to joining academia, he was a senior processor architect at Intel Corporation and later the architecture manager of StarCore DSP Center, a joint design center of Lucent/Agere systems and Motorola. Dr. Lee's doctoral thesis was awarded the Horace H. Rackham School Distinguished Dissertation Award at the University of Michigan. He has co-authored three papers that won Best Paper Awards at MICRO-33, CASES-04, and IBM PAC^2. More recently, Dr. Lee received the Department of Energy Early CAREER PI Award and was named the recipient of the 2006 ECE Outstanding Jr. Faculty Member Award at Georgia Tech. Dr. Lee holds 4 U.S. patents and is a member of Tau Beta Pi, the ACM and the IEEE.
