Abstract
Embodiments may include receiving a protected version of content that includes multiple encryption chains each including encrypted blocks of content. The protected version of content may include one or more initialization vectors for decrypting the encrypted blocks of content and discard information that specifies non-content portions of one or more data blocks to be discarded after decryption. Embodiments may also include performing chained decryption on the multiple encryption chains using the initialization vectors specified by the decryption information. The chained decryption may result in a sequence of decrypted data blocks. Embodiments may also include, based on the discard information, locating and removing the non-content portions of one or more data blocks in the sequence of decrypted data blocks. Embodiments may also include generating the protected version of content. Embodiments may also include performing any of the aforesaid techniques on one or more computers.
