Abstract

The invention discloses a user trust device capable of network update. A user trust device (10) comprising: a connection interface; and a persistent storage (14), wherein the network updater (15) is configured to communicate with firmware (122) of the host computer (101) when executed at the host computer (101) interact to initiate communication, and the boot enablement data structure (16) can be detected by the firmware (122) if the user trusts the device (10) to be connected to said host computer (10); enabling the host computer (101) to boot from the user-trusted device (10); and contain instructions for the firmware (122) to boot said network updater (15) onto the host computer (10) if the host computer is booted from the user-trusted device transmission for subsequent execution at the host computer (101).

Description

technical field [0001] The present invention relates generally to the field of user-trusted devices equipped with a connection interface for connection to a host computer, and in particular to a software update method for updating such devices over a network. Background technique [0002] User-trusted devices (including secure, tamper-resistant devices) are generally known. For example, for online transactions, one developed scheme is the so-called Zone Trusted Information Channel (or ZTIC for short). ZTIC is a secure, non-programmable device for transaction data authentication. Since ZTIC maintains a secure end-to-end network connection with the server, ZTIC itself is tamper-resistant against malware attacks, and since it has its own input and output components independent of the host it is connected to, the ZTIC The data shown on the display is true. For more details see e.g. The Zurich Trusted Information Channel – An Efficient Defense against Man-in-the-Middle and Mal...
