Hi there 👋

I am Jun Kurihara, a research engineer in the area of distributed systems and networking in Japan and sometimes in US. I am really interested in developing novel software and networking products/services written in various languages on various infrastructures. You can reach me via my LinkedIn or WebSite.

Mutualized Oblivious DNS (μODNS)

Currently I am really interested in the enhancement of privacy-preserving DNS architectures. As one of my research activities, I am actively developing Mutualized Oblivious DNS by extending existing sophisticated encrypted and anonymized DNS protocols.
