Conditional Access

The security technologies for the home entertainment and digital media market are based on a wide variety of Conditional Access (CA) security such as DVB, ISDB and OpenCable and Digital Rights Management (DRM) and content protection schemes.

Elliptic offers highly integrated and proven security solutions spanning silicon cores to embedded software to help content owners, service providers, network operators, embedded system OEMs and SoC suppliers protect high-value digital content for the home entertainment and digital media market.

Conditional access systems are developed for use in cable television, satellite systems and now IPTV applications. In an attempt to keep their conditional access systems immune from hacking, network operators have often implemented proprietary security designs. The most successful attempt to standardize conditional access is DVB which stands for Digital Video Broadcasting. DVB standards are maintained by the DVB Project and they are published by a Joint Technical Committee (JTC) of the European Telecommunications Standards Institute (ETSI), the European Committee for Electrotechnical Standardization (CENELEC) and the European Broadcasting Union (EBU). The conditional access system (DVB-CA) defines a common scrambling algorithm (DVB-CSA) and Elliptic has released solutions supporting CSA descrambler version 2 (CSA2) and version 3 (CSA3).

Elliptic has also implemented the MULTI2 algorithm used in the conditional access system known as CS-Digital broadcast in Japan.
