Unlikely Friendships: The Fruitful Interplay of Cryptographic Assumptions
Dr. Shweta Agrawal is an associate professor at the Computer Science and Engineering department, at the Indian Institute of Technology, Madras. She earned her PhD at the University of Texas at Austin, and did her postdoctoral work at the University of California, Los Angeles. Her area of research is cryptography and information security, with a focus on post quantum cryptography. She has won multiple awards such as the Indian national Swarnajayanti award and a best paper award at Eurocrypt.
Approximate Computation on Encrypted Data
Jung Hee Cheon is a professor in the department of mathematical sciences and the director of the Industrial and Mathematical Data Analytics Reseach Center (IMDARC) in Seoul National University (SNU). He received his B.S. and Ph.D. degrees in mathematics from KAIST in 1991, and 1997, respectively. Before joining SNU, he worked for ETRI (senior researcher), Brown University (visiting scientist) and ICU (assistant professor).
He has been working on computational number theory, cryptology, and information security. In those area, he published more than 50 journal papers and many conference papers including 18 Crypto/Eurocrypt/Asiacrypt, which are the most prestigious conferences for Cryptology. He is one of the co-inventors of braid cryptography and (independently) Xedni calculus on elliptic curve discrete logarithms. His works on improved Pollard rho algorithm and an efficient algorithm on strong DH problem drew many attentions, the former of which won the best paper award in Asiacrypt 2008. He received the best paper award in Eurocrypt 2015 for this joint work on cryptanalysis of multilinear maps. As one of co-inventors of approximate homomorphic encryption HEAAN, he is actively working on homomorphic encryptions and their applications including machine learning on encrypted data, homomorphic control systems, and DNA computation on encrypted data.
He is an associate editor of "Design, Codes and Cryptography", "Journal of Communication Network" and "Journal of Cryptology" that is the flagship journal in Cryptology. He co-chaired ANTS-XI, Asiacrypt 2015/2016 and MathCrypt 2018/2019 and served as program committee for numerous crypto conferences including Crypto, Eurocrypt, Asiacrypt and so on. He was selected as Scientist of the month by Korean government in 2018 and won the POSCO science prize in 2019.
