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).
