Wireless broadcast is an effective approach for spreading data widely to a number of users. To provide secure transmission, symmetric-key-based encryption is one of the widely used method, that ensures only valid users can decrypt the data. With regard to various subscriptions, an efficient key management for distributing and changing keys is needed to control broadcast services. In this paper, the authors propose an efficient key management scheme, namely, Secured Tree Based Key Management (STBKM), to handle key distribution with regard to complex subscription options and user activities. STBKM needs to hold one set of keys for all subscription activities in wireless broadcast services.
