Abstract:
1. A method for storing an identifier in a first station having a secure non-volatile data store protected by cryptographic data, an identifier flag for indicating that the identifier has been written to the secure non-volatile data store, and an authenticated trust agent that prohibits writing of an identifier to the secure non-volatile data store when the identifier flag is set, the method comprising: writing the identifier to the secure non-volatile data store, wherein the identifier written to the secure data store is encrypted using the cryptographic data; and irreversibly setting the identifier flag after writing the identifier to the secure non-volatile data store so that the authenticated trust agent prohibits another write of an identifier to the secure non-volatile data store, wherein the first station further comprises an authenticated operating system including the authenticated trust agent such that the authenticated trust agent is a software element of the authenticated operating system.
