摘要：
Due to the use of commodity software and hardware, crash-stop and Byzantine failures are likely to be more prevalent in today's large-scale distributed storage systems. Regenerating codes have been shown to be amore e_cient way to disperse information across multiple nodes and recover crash-stop failures in the literature. In this talk, we present the design of regeneration codes in conjunction with integrity check that allows exact re-generation of failed nodes and data reconstruction in the presence of Byzan-tine failures. A progressive decoding mechanism is incorporated in both procedures to leverage computation performed thus far. The fault tolerance and security properties of the schemes are also analyzed.
個人簡介：
Yunghsiang S. Han received B.Sc. and M.Sc. degrees in elec-trical engineering from the National Tsing Hua University, Taiwan, in 1984 and 1986, respectively, and a Ph.D. degree from the School of Computer
and Information Science, Syracuse University, NY, in 1993. He was with Hua Fan College of Humanities and Technology, National Chi Nan Univer-sity, and National Taipei University, Taiwan. From August 2010, he is with the Department of Electrical Engineering at National Taiwan University of Science and Technology.
Dr. Han's research interests are in error-control coding, wireless net-works, and security. Dr. Han has conducting state-of-the-art research in the area of decoding error-correcting codes for more than sixteen years. He_rst developed a sequential-type algorithm based on Algorithm A* from ar-ticial intelligence. At the time, this algorithm drew a lot of attention since it was the most e_cient maximum-likelihood decoding algorithm for binary linear block codes. Dr. Han has also successfully applied coding theory in the area of wireless sensor networks. He has published several highly cited works on wireless sensor networks such as random key pre-distribution schemes. He also serves as the editors of several international journals.
Dr. Han was the winner of the Syracuse University Doctoral Prize in 1994 and a Fellow of IEEE.
