Transit Management Center --> Personal Information Device:
registered secureIDs
Definitions
registered secureIDs (Information Flow): Cryptographically protected identifier indicating that the user associated with the identifier is entitled to use a particular service.
Transit Management Center (Source Physical Object): The 'Transit Management Center' manages transit vehicle fleets and coordinates with other modes and transportation services. It provides operations, maintenance, customer information, planning and management functions for the transit property. It spans distinct central dispatch and garage management systems and supports the spectrum of fixed route, flexible route, paratransit services, transit rail, and bus rapid transit (BRT) service. The physical object's interfaces support communication between transit departments and with other operating entities such as emergency response services and traffic management systems.
Personal Information Device (Destination Physical Object): The 'Personal Information Device' provides the capability for travelers to receive formatted traveler information wherever they are. Capabilities include traveler information, trip planning, and route guidance. Frequently a smart phone, the Personal Information Device provides travelers with the capability to receive route planning and other personally focused transportation services from the infrastructure in the field, at home, at work, or while en-route. Personal Information Devices may operate independently or may be linked with vehicle on-board equipment. This subsystem also supports safety related services with the capability to broadcast safety messages and initiate a distress signal or request for help.

Basis | These IDs are used to secure individual user's rights to use transportation assets. Compromising one of these would be a significant inconvenience but only for the user of that secureID. However, compromise of the algorithm securing all IDs would be catastrophic to the system that uses this mechanism as a means to pay for transportation services. | Individual tokens should be correct or the user will not be able to use this method to pay for transport. A systemic integrity flaw would compromise the system similar to how an encryption flaw would however, which justifies HIGH. | Should be relatively infrequently used by any one user, but over the sum of all transport users sees significant use. If the flow is not available, new or re-applying users will not be able to use this method to pay for transport. |
