Mobile phones security is becoming an important issue because they are being connected to an Internet through wireless modem technologies. System virtualization technology provides trusted computing capability by running isolated multiple virtual machines under hypervisor. In this paper, the authors propose a design of system virtualization for ARM CPU architecture and describe implementation of prototype called Xen on Arm using Xen hypervisor. Secure and nonsecure guest Linux virtual machines are executing under Xen on ARM isolated with each other and virtualization overhead is shown to be moderate compared to native Linux running on bare metal H/W.
