Smarter than a Smart Card

Eliminate costs in set-top boxes with a hardware root-of-trust that offers security protection with a security core that decreases potential attack vectors.


Set-top boxes (STBs) were initially secured by Conditional Access System (CAS) smart cards. However, this approach is no longer effective. Smart cards cannot prevent unauthorized access to premium 4K and UHD content, as they are not designed to protect the interface between the card and box, or the STB SoC itself. This is one of the reasons why cardless CAS set-top boxes, equipped with a hardware-based root-of-trust, are increasing in popularity amongst major operators such as Dish TV India. A hardware root-of-trust, provided by platforms such as Rambus’ CryptoMedia, offers operators robust security protection with an integrated security core that acts to effectively decrease potential attack vectors. Moreover, eliminating the smart card significantly reduces cost, for both short-term BOM and long-term liability in the form of frequent card swaps.
