Cardless conditional access systems must still fallback on hardware as part of their defence against possibly malicious attacks, says a new White Paper.
Cardless Without Compromise, produced by security specialists Nagra and available from the Broadband TV Newswebsite says leading academics agree that software-based systems are not fully robust against tampering and reverse engineering.
The solution must rely on systems that use a combination of proprietary key ladders and algorithms, and not on the standard E TSI key ladder, which as an open standard is more vulnerable to attack.
The White Paper traces the evolution of the cardless system since the launch of the first multi-channel IPTV service by Kingston Interactive Television (KIT) in the UK in 1999 and the format’s subsequent acceptance on one-way systems such as satellite.
It was once thought that the closed nature of IPTV networks provided some protection against content theft by the nature of the network architecture itself, meaning that the IPTV security solutions did not historically need to be as robust as their broadcast counterparts. However, this is beginning to change with high-profile attacks against media companies like Sony and others.
