Hoeteck Wee
Senior Scientist
I am a Senior Scientist at NTT Research, and a CNRS Senior Researcher at ENS, Paris. I received my PhD from UC Berkeley and my BSc from MIT. My research addresses new cryptographic challenges posed by Big Data and the Internet. My recent works focus on advanced encryption schemes that support fine-grained access control and selective computation; I am also a contributor to the TLS 1.3 standard.
