Method, apparatus and computer program product for providing mobile broadcast service protection
First Claim
1. A method comprising:
- receiving an indication of device groupings defining at least a first group of devices and a second group of devices in which the first and second groups are defined on the basis of a device characteristic;
communicating a first security key providing access to a first message stream associated with a mobile broadcast service to the first group of devices; and
communicating a second security key providing access to a second message stream associated with the same mobile broadcast service to the second group of devices in which the first and second security keys are different.

Abstract
An apparatus for providing mobile broadcast service protection may include a processor. The processor may be configured to receive an indication of device groupings defining at least a first group of devices and a second group of devices in which the first and second groups are defined on the basis of a device characteristic, communicate a first security key providing access to a first message stream associated with a mobile broadcast service to the first group of devices, and communicate a second security key providing access to a second message stream associated with the same mobile broadcast service to the second group of devices. Methods and computer program products corresponding to the apparatus are also provided from the perspective of a network device and mobile terminal.
