摘要:
The present embodiments advantageously provide methods and systems for use in decrypting content, and in some preferred embodiments expanding a security environment to distribute the computational processing involved in decryption. In some embodiments, a method for use in decrypting content is provided that receives a first content key at a first system for the decryption of a first track of encrypted content; encrypts the first content key according to a first instance key known at the first system; communicates the first encrypted content key over an externally accessible communication link to a second system; generates the first instance key at the second system independent of the first system; decrypts the first encrypted content key using the generated first instance key at the second system; and decrypts the first track of encrypted content using the first unencrypted content key at the second system.
