Abstract
An access platform or other network elements can include multiple line cards configured to encrypt data. The platform and/or each of the line cards may receive encryption management data that conforms to a predefined encryption management data interface. The encryption management data received by a particular line card may be generated by a conditional access system device and converted to conform to the encryption management data interface by an encryption manager. Line cards may alternatively be configured for connection to separate encryption hardware components. Line cards may include a block of field programmable gate arrays or other type of programmable hardware that can be configured to execute an encryption module.
