2012-02-29 CERIAS - Cryptographic protocols in the era of cloud computing

Recorded: 02/29/2012 CERIAS Security Seminar at Purdue University Cryptographic protocols in the era of cloud computing Nishanth Chandran, Microsoft Research With the advent of cloud computing, our view of cryptographic protocols has changed dramatically. In this talk, I will give an overview of some of the newer challenges that we face in cloud cryptography and outline some of the techniques used to solve these problems. In particular, a few questions that I will address are:1) How can we store sensitive data in the cloud, in an encrypted manner, and yet allow controlled access to certain portions of this data?2) How can we ensure reliability of data across cloud servers that may be connected by only a low-degree communication network, even when some of the servers may become corrupted?3) How can users authenticate themselves to the cloud in a user-friendly way?This talk will assume no prior knowledge of cryptography and is based on works that appear at TCC 2012, ICALP 2010 and STOC 2010. Nishanth Chandran is a post-doctoral researcher in the Cryptography group at Microsoft Research, Redmond. His research interests are in the area of cryptography, security and distributed algorithms. Nishanth has published several papers in top theory and cryptography conferences such as STOC, FOCS, Crypto, Eurocrypt, TCC and so on. He received his PhD in Computer Science from UCLA in 2011, his Masters in Computer Science from UCLA in 2007, and his Bachelors in Computer Science and Engineering from Anna University, India in 2005. Nishanth received the Dissertation Year Fellowship from UCLA and the Chorafas International Award for exceptional achievements in research in 2010. He is also a professional Indian classical violinist. (Visit: www.cerias.purude.edu)
