Group Key Management for Secure Mobile IPTV Service

In this paper, we propose an energy-efficient and secure channel group key establishment and rekeying management scheme for mobile IPTV service. Compared with traditional IPTV service, mobile IPTV is much more vulnerable to various attacks, and membership management is more complicated because of the user mobility. Our scheme provides a group key management mechanism that supports authentication between eNB and the mobile devices for security enhancement and efficiently rekeys the group key when membership changes. Our proposal can cope with the security vulnerability of mobile IPTV for reliable group communication and guarantees secure group key rekeying in addition to decreasing the storage and communication overhead.
