- Abstract
- The evolution of internet have opened the world of IPTV. With internet protocol, IPTV broadcasts contents stream. The IP protocol doesn't provide secure service due to IP characteristics. So, it is important to provide both connect and secure service. Conditional Access System and/or Digital Right Management are being used to protect IPTV contents. However, there exist restrictions in the view of security. In this paper, we analyse existing security technologies for IPTV and propose a novel method to enforce security efficiently. In the proposed method, OTP is used for encryption/decryption contents and CAS controls key for encryption/decryption and the right of user. With this scheme, it reduces the load of the system and provides more security.
