METHOD OF ESTABLISHING A TRUSTED IDENTITY FOR AN AGENT DEVICE

摘要

A trusted identity may be established for an agent device (4) for performing trusted communication with one or more application providing apparatuses (6). The method of establishing the trusted identity includes determining which of a number of authentication models is a selected authentication model to be used for uniquely authenticating the agent device (4)(100). First and second authentication information is generated according to the selected model (102). The first authentication information is for uniquely authenticating the identity of the device and the second authentication information is for verifying that the agent device has the first authentication information. The first authentication information is embedded in the agent device (4)(104) while the second authentication information is transmitted to a registry apparatus (8)(106) for maintaining a device of agent devices. Authentication model information identifying which is the selected authentication model is also sent to the registry (8)(106).
