Identifying traffic associated with a content provider's toll-free data service campaign

摘要

A device may receive, from a mobile device, first encrypted information, encrypted by a content provider device using a first private key, and at least one unencrypted identifier. The device may decrypt, using a first public key, the first encrypted information to obtain first information that may include second encrypted information, encrypted using a second public key. The device may decrypt, using a second private key, the second encrypted information to obtain second information that may include at least one first identifier and at least one second identifier corresponding to a toll-free data service campaign that may be provided by a content provider. The device may allow toll-free data service traffic, for the mobile device, based on whether the at least one first identifier corresponds to the at least one unencrypted identifier and the traffic includes at least one third identifier that corresponds to the at least one second identifier.
