The posts in this blog were written during my time as a PhD student in Computer Science at the University of Tsukuba under the supervision of Prof. Hiroyuki Kitagawa and Prof. Toshiyuki Amagasa.
It contains information about my publications, summaries of papers I read, discussions about theoretical concepts and programming tutorials.
Since I changed the focus of my career, this blog will not be updated anymore, but I believe the contents may be helpful to others interested in database security and homomorphic encryption, so I will leave it online.
