There are possible attacks and network outage
failures for IPTV services. Rapid recovery after
attacks/failures is important to minimize negative impact. IPTV services should provide user
security and privacy with confidential delivery of
data such as program channels and content, prevention of attacks from malicious users/software,
and denial of service (DoS).
Designing secure and anonymous IPTV services requires further investigation and research.
Especially, the following issues must be solved:
distributed digital rights management (DRM) to
protect the copyright of video contents, the
authentication of clients to verify their access
privileges, and the prevention of traffic flooding
/ bandwidth over-consumption attacks.
