Designed to cost-effectively secure the broadcast and streaming of digital content, our CryptoMedia Content Protection Core provides pay TV operators and over-the-top (OTT) media providers robust security against security threats, like side channel attacks, through a hardware root-of-trust embedded directly in the device multimedia chipset. The core enables a cardless solution that is compatible with existing conditional access systems (CAS) and digital rights management implementations.


CryptoMedia Content Protection Core provides side channel attack resistance in a wide variety of ecosystem configurations:
  • In broadcast systems: the core receives the data it needs for operation in standard encrypted messages via infield provisioning from the CAS, including: pay-per-view (PPV) and subscription updates and security configurations.
  • In OTT systems: the core is configured via license files that are updated via infield provisioning to enable feature upgrades.
  • In CAS: the core is designed to work with a variety of CAS providers as it can either help derive or directly generate the control word and deliver it into the key ladder or descrambler.
  • In DRM systems: as with CAS providers, the core functions with diverse DRM systems. The operation is similar to the CAS, except the derived key is the content encryption key that is delivered to an AES decryption engine. In both cases, generation and derivation of the control word or content encryption key is handled in secure, protected hardware.
