Abstract: In an approach to allowing a computer to boot from a user trusted device (UTD), the computer comprises a data storage device storing operating system (OS) services, and a version of an OS loader. The UTD is connectable to the computer and stores a boot loader, detectable by a firmware executing at the computer, and an OS loader, and wherein the UTD prevents an unauthenticated user to modify the boot loader and the OS loader stored thereon. The computer then, upon connection, lets the boot loader be detected by the firmware for execution of the boot loader at least partly at the computer, to cause to transfer the OS loader from the UTD to the computer, and executes the transferred OS loader at least partly from the computer, to execute at least one crypto driver for the OS, to start the OS services and complete booting of the computer.

Abstract: Methods and apparatus are provided for provisioning an operating system image from a server (2) to an untrusted user terminal (4) via a data communications network (3). A trusted device (5) such as a pocket USB device has tamper-resistant storage (9) containing bootloader logic, for controlling booting of a user terminal, and security data. On connection of the trusted device (5) to an untrusted user terminal (4), the user terminal is booted via the bootloader logic on the trusted device. Under control of the bootloader logic, a connection is established to the server (2) via the network (3) and the server is authenticated using the security data on the trusted device (5). An operating system boot image is received from the server (2) via this connection. The boot image is used to provision an operating system image from the server (2) to the user terminal (4) for execution of the operating system at the user terminal (4).
