Achieving IPTV service portability through delegation

Open IPTV has attracted considerable attention and is expected to bring great changes in the IPTV service area. However, because of its openness and IP network characteristics, security is one of the major issues hindering its commercialization. For IPTV, several security mechanisms for user authentication and content protection have been applied to make the service reliable. These traditional security mechanisms cannot be adopted in the IPTV area, because in the many-to-many environment the security and hence the system performance is influenced by numerous factors. In our work, we propose a mechanism for secure user authentication and key distribution based on Kerberos for open IPTV and for secure M2M three-screen service in home networks. Our proposal provides an efficient authentication process and secure transfer of contents among users, and it further decreases the authentication time compared with the other mechanisms.

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.

Openness has been added to IPTV (Internet Protocol Television) services in order for users not only to receive, but also to provide them. Open IPTV is expected to bring about great changes in the IPTV service area. Recently, mobility has also been added. However, because of its openness and IP network characteristics, security is one of the major issues hindering its commercialization. For IPTV, several security mechanisms for user authentication and content protection have been proposed to make the service reliable. However, these traditional security mechanisms cannot be adopted in the mobile IPTV area, because the security and system performance are influenced by numerous factors in the many-to-many environments. In our work, we propose a mechanism for secure user authentication and key distribution based on Kerberos for mobile open IPTV. Our proposal provides an efficient authentication process and the secure transmission of content among users, and further decreases the authentication time compared with that of other mechanisms.
