Future Plan

Our main target is to analyze the security of public key cryptosystems from a theoretical perspective. Furthermore, we will also analyze the security of existing systems.
Messages to Students
I hope that you will try to voraciously acquire a broad range of knowledge.
You need not self-restrict your potential.
