CryptoMedia Content Protection Services

Designed to complement our CryptoMedia Content Protection Core (CPC) as a cost-effective digital content broadcast and streaming security platform, our CryptoMedia Content Protection Services (CPS) provide pay TV operators and over-the-top (OTT) media providers robust security infrastructure integration for cryptographic data delivery. The CPS allows for the conditional access systems (CAS) and DRM to be quickly and easily integrated with the CPC, reducing time to market and enabling dramatically reduced cost cardless set top box (STB) design.

How it works

The CPS provides infrastructure that seamlessly integrates on the headend with industry standard CAS and DRM solutions to provide the cryptographic data for digital content security using the CPC. The cryptographic data is either generated by the CPS or stored and sent to the headend in order to encrypt the video stream. The CPS then interfaces with the CPC for the video decryption in the STB.

We also provide engineering services and technical support during and after installation to ensure rapid system deployment.

CryptoMedia Content Protection Services augments system security against side channel attacks and support for a wide variety of system configurations and applications:

Headend CryptoManager (HCM) Server: the HCM Server is a specialized rack mount appliance that provides a secure mechanism for generating the cryptographic data needed to secure the digital content. It interfaces with the CAS and provider’s headend to give the cryptographic keys for encryption and decryption in a cardless STB.

Differentiation Vector (DV): these are device specific encrypted messages that are generated by Rambus Security and stored in the content provider’s headend which configure the CPC with the proper data for content decryption.

Encrypted Rights Key (ERK): Similar to the DV, the ERK is an encrypted message that authorizes specific content to be accessible for a specified period of time for use in pay per view (PPV) or subscription applications. ERKs are either generated directly by the HCM Server or by Rambus Security and stored in the provider’s headend.

Integration and Support Services: in order to reduce the costs and time associated with system integration, we offer engineering services to help get your STB design and security infrastructure up and running as quickly as possible. Additionally, we have a 24/7-support service to maximize your system uptime and minimize service disruptions.

Our CryptoMedia CPS solutions are designed to seamlessly integrate with a cardless STBs, Smart TVs and other devices using our CPC that is embedded in the multimedia chipset to provide robust device security. The combination of the CPS and CPC allows for content providers to securely protect their content and easily provide service tier and PPV content to their customers via a robust hardware root of trust. Additionally, our professional services decrease the time to integrate our solutions into your security ecosystem and provide support should you need it.

DPA Countermeasures

security-icon
DPA Countermeasures are fundamental techniques for protecting against Differential Power Analysis (DPA) and related side-channel attacks. Consisting of a broad range of software, hardware, and protocol techniques, DPA Countermeasures include reducing leakage, introducing amplitude and temporal noise, balancing hardware and software, incorporating randomness, and implementing protocol level countermeasures.
