Selective encryption with coverage encryption: Brant L. Candelore


Selective encryption is a technique to save computational complexity or enable interesting new system functionality by only encrypting a portion of a compressed bitstream while still achieving adequate security. This project finds a method to provide selective encryption with coverage encryption.  This project deals with A method and apparatus for enabling use of multiple digital rights management scenarios (DRM),where DRM (Digital rights management) is a class of access control technologies that are used by hardware manufacturers, publishers, copyright holders and individuals with the intent to limit the use of digital content and devices after sale.

Unencrypted data representing digital content is examined to identify at least segments of content for DRM encryption. The identified segments of content are duplicated and then encrypted using a first encryption method associated with a first DRM to produce first encrypted segments. Duplicates are encrypted using a second encryption method associated with a second DRM to produce second encrypted segments. At least a portion of segments not selected for DRM encryption are encrypted using a coverage encryption method. The coverage encryption key is encrypted by each of a third and fourth encryption methods associated with the first and second DRMs respectively.
