Research Interests

In my reasearch I am investigating how the security and trustworthyness of commodity operating systems as Windows or Linux can be enhanced. To accomplish this, I focus onto two technologies: First, trusted platforms, and second, virtualization of the underlying hardware.

Trusted platforms allow to measure the state of a system and to provide authentic evidence for that state. In addition, critical data as cryptographic keys can be bound to that state, e. g., using the trusted platform module.

System virtualization provides strong isolation of different virtual machines on one physical host. It allows to monitor their state, intercept certain activities, and to reset the machine back to a trusted state, if necessary.
Projects

InSight logoFor my research in the field of virtual machine introspection, I developed a powerful tool, InSight, for bridging the semantic gap between hypervisor and guest operating system. InSight has already been applied to several projects at our chair and proven to be a flexible, high-performance, and stable means of re-constructing kernel objects out of guest physical memory. In the meanwhile, InSight has been released to the public and is licensed to the terms and conditions of the GNU GPLv2.

For more information visit the project website of InSight hosted at Google Code.
