A security system is applied to venue-cast content transmissions over a broadcast/multicast network infrastructure. The broadcast network infrastructure may be Evolution-Data Only Broadcast Multicast Services (BCMCS) that facilitates distribution of a subscription-based content delivery service. A venue-cast service can be part of the subscription-based content delivery service and has an associated service key. Upon subscribing to the content delivery service, the subscriber access terminal is given the service key. Such service key may be associated with a particular subscriber package and/or venue location. The same service key is provided to the broadcast network infrastructure that broadcasts venue-cast content. A broadcast access key is generated by the broadcast network infrastructure and used to encrypt venue-specific content to be broadcasted. Consequently, only access terminals that have received the service key (e.g., subscribe to the associated subscription package and/or are located at a specific venue or location) can decrypt the broadcasted content. |
