Abstract
Encrypted compressed content is produced by encrypting content based at least in part on a content key, and compressing the content based at least in part on the content key. Thus, the content key is employed to encrypt the content and also to compress the content. Similarly, decrypted decompressed content is produced from the encrypted compressed content by decrypting the content based at least in part on a content key, and decompressing the content based at least in part on the content key. Thus, the content key is employed to decrypt the content and also to decompress the content.
