Registration Authority

IEEE offers Registration Authority programs or registries which maintain lists of unique identifiers under standards and issue unique identifiers to those wishing to register them. The IEEE Registration Authority assigns unambiguous names to objects in a way which makes the assignment available to interested parties.

IEEE 1667 SILO TYPE IDENTIFIER (STID)

IEEE 1667 specifies the interface to and behavior of several silos (e.g., Probe Silo, TCG Storage Transport Silo, Password Silo, and Smart Card Transport Silo). External silos may be defined outside of the standard, be either public or private, and involve third-party licensing. Guidelines for external silos are specified in IEEE 1667.
