[Invited Talk] Foundations and practical studies of secure computation
Ryo Kikuchi (NTT) ISEC2017-78 COMP2017-32
Abstract (in Japanese) (See Japanese page) 
(in English) Secure computation, also known as secure multiparty computation, is a method to compute a function on encrypted data. This method attracts attention since it enables privacy-preserving data analysis on sensitive data. Although secure computation had not been used in practice due to its inefficiency, the efficiency of secure computation has been improved greatly, and recently several implementations are used in practice.
In this talk, we provide brief introduction of secure computation, and several studies for improving efficiency. Especially, we try to explain why secure computation will be inefficient, why we require a tailor-maid algorithm for secure computation, and how to construct it.
