Abstract
A portable secured computing environment for performing online confidential transactions in an untrusted host computer. The secured computing environment may be loaded from a portable storage device, such as a USB stick, plugged into a peripheral port of the host computer. The secured computing environment may include a virtual machine running under a host operating system of the host computer. A secured operating system may be running in the virtual machine.
