Abstract

A mobile terminal is configured to acquire an encryption key to decrypt a pay channel encrypted with a smartcard profile by the mobile terminal in a Multimedia Broadcast/Multicast Service (MBMS) mobile broadcast system. The mobile terminal is configured to purchase a specific pay channel, determine validity of an encryption key, store a range of a valid encryption key identification value, and initialize a reference Time Stamp (TS) value. The mobile terminal also; extracts an encryption key identification value and a TS value from a last received Short Term Key Message (STKM), when a view request for the specific pay channel is created; and determines that an encryption key is valid, when the extracted TS value satisfies the reference TS and the extracted encryption key identification value falls within a range of the valid encryption key identification value, and extracts and acquires an encryption key from the STKM.
