ABSTRACT:
A system for authorizing information services that are provided via broadcast messages to mobile stations. The broadcast messages are encrypted prior to being communicated to devices within a geographic area. The mobile stations are provided with a client application that retrieves cryptographic keys associated with the information services to which a customer is subscribed. When the mobile station receives encrypted broadcast messages, the client application determines if it has the cryptographic key to decrypt the message. If so, the information contained in the message is displayed. If not, then the message is ignored by the mobile station.
