CryptoFirewall solution supports various systems:
In broadcast systems: the core receives the data it needs for operation in standard encrypted messages from the conditional access system.
In OTT systems: data for the core is typically sent in license files during the provisioning of the device.
In CA systems: the core can either derive or generate the control word and deliver it into the DVB-CSA descrambler. For derivation of the control word, the core delivers a key into the key ladder.
In DRM systems: operation is similar to the CA system, except the key that is being derived is the content encryption key and is usually delivered to a bulk AES decryption engine. In both cases, generation and derivation of the control word or content encryption key is handled in secure, protected hardware.
Our CryptoFirewall solution supports a multi-domain security feature that is unique to our core and is based on an advanced hardware root-of-trust. This innovative feature allows premium content to flow securely from the cloud directly to pay TV devices like STBs, forming a secure foundation for convenient access to all pay TV content on one device. It enables new ways to distribute pay content, providing benefits to both operators and OTT distributors:
- Operators can provide their subscribers with instant individual choice of content on the STB or TV
- OTT distributors can deliver content directly and securely to operator STBs and TVs
