VIRTUS: a new processor virtualization architecture for security-oriented next-generation mobile terminals

The authors propose new processor virtualization architecture, VIRTUS, to provide a dedicated domain for pre-installed applications and virtualized domains for downloaded native applications. With it, security-oriented next-generation mobile terminals can provide any number of domains for native applications. VIRTUS feature three new technologies: VMM asymmetrization, dynamic inter-domain communication and virtualization-assist logic, and the first in the world to virtualize an ARM-based multiprocessor.
