Seminar

Abstract: Secure Multi-party Computation (MPC), the standard-bearer and holy-grail problem in Cryptography, permits a collection of data-owners to compute a collaborative result, without any of them gaining any knowledge about the data provided by the other, except what is derivable from the final result of the computation. The first half of the talk will discuss garbled circuits and Yao's two-party computation. in the second half, if time permits, then I will discuss one of our recent works on MPC with small population and honest majority that builds on garbled circuits.-----Brief Bio: Dr Arpita Patra is an Assistant Professor at Indian Institute of Science. Her area of interest is Cryptography, focusing on theoretical and practical aspects of secure multiparty computation protocols. She received her PhD from Indian Institute of Technology (IIT), Madras and held post-doctoral positions at University of Bristol, UK, ETH Zurich, Switzerland and Aarhus University, Denmark. Her research has been recognized with an NASI Young Scientist Platinum Jubilee Award, a SERB Women Excellence award, an INAE Young Engineer award and associateships with various scientific bodies such as Indian Academy of Sciences (IAS), National Academy of Engineering (INAE ), The World Academy of Sciences (TWAS).
