BitVisor: a thin hypervisor for enforcing i/o device security
Takahiro Shinagawa,Hideki Eiraku,Kouichi Tanimoto,Kazumasa Omote,Shoichi Hasegawa,Takashi Horie,Manabu Hirano,Kenichi Kourai,Yoshihiro Oyama,Eiji Kawai,Kenji Kono,Shigeru Chiba,Yasushi Shinjo,Kazuhiko Kato +13 more
TL;DR: A hypervisor architecture, called parapass-through, designed to minimize the code size of hypervisors by allowing most of the I/O access from the guest operating system (OS) to pass-through the hypervisor, while the minimum access necessary to implement security functionalities is completely mediated by thehypervisor.

Manabu Hirano,Takahiro Shinagawa,Hideki Eiraku,Shoichi Hasegawa,Kazumasa Omote,Kouichi Tanimoto,Takashi Horie,Kazuhiko Kato,Takeshi Okuda,Eiji Kawai,Suguru Yamaguchi +10 more
TL;DR: This paper especially introduces Role-based Access Control (RBAC) to the ID management framework in a secure VMM system and shows design and prototype implementation based on PKI-based ID card and proven open source VMM software, QEMU.

Manabu Hirano,Takahiro Shinagawa,Hideki Eiraku,Shoichi Hasegawa,Kazumasa Omote,Koichi Tanimoto,Takashi Horie,Seiji Mune,Kazuhiko Kato,Takeshi Okuda,Eiji Kawai,Suguru Yamaguchi +11 more
TL;DR: The proposed two-step execution mechanism can reduce run-time codes of a hypervisor and is shown showing a design, a prototype implementation and measurement results of lines of code using BitVisor, a VMM-based TCB developed.

Information processing system, program for information processing system, and access control method for client device
Takahiro Shinagawa,Hideki Eiraku,Men Kazunari,Koichi Tanimoto,Shoichi Hasegawa,Takashi Horie,Kazuhiko Kato +6 more
TL;DR: In this paper, the authors propose a solution to provide a highly secure information processing system without complicating a virtual machine monitor by configuring the virtual machine Monitor VM to accept access from the guest operating system OS and capture only the access required for achieving a security function while allowing the access unnecessary for implementing the security function to the hardware HW.
