Abstract
In a transient storage device (TSD) with multiple authentication silos, a host computing device connected to the TSD is configured by the TSD to discover and act upon various types of authentication information in the silos. One or more logical combinations of authentication silos are switched to the authenticated state to grant access to an associated storage area. A particular ordering of authentication silos may be required to achieve a valid combination of authenticated silos. Ordering may be suggested by configuration information in the TSD. Ordering may also be based upon whether or not user input is required for authenticating a given authentication silo, the environment of use of the TSD, or a hierarchy from most trusted to least trusted authentication silo. With this information, the host proceeds with the most efficient authentication sequence leading to a grant of access to the storage area.
