TLDR
In this article, a content distribution system includes a data processing apparatus of a user for receiving a content supplied from a content transmitter, and a communication network connecting the data processing apparatuses of the user and the third party for mutual data communication.Abstract:
A content distribution system includes a data processing apparatus of a user for receiving a content supplied from a content transmitter, a data processing apparatus of a third party trusted by both the content transmitter and the user, and a communications network connecting the data processing apparatuses of the user and the third party for mutual data communication The data processing apparatus of the user is provided with a tamper-resistant device storing data inaccessible from outside The data processing apparatus of the third party transmits first data to the data processing apparatus of the user, wherein the first data relates to an encryption key that decodes a cipher generated by the content transmitter The encryption key is obtained only within the tamper-resistant device The tamper-resistant device decodes the cipher by using the first data from the data processing apparatus of the third partyread more

Digital rights management (DRM) encryption and data-protection for content on device without interactive authentication
TL;DR: In this article, the authors propose a method to render content on a medium, where a device obtains a table from the medium, obtains the private key of the device (PR-PD), indexes into an entry of the table based on the table, and applies (PD) to (PD(RND) to expose a random key (RND).

Patent
Multi-factor content protection
TL;DR: In this paper, the content is encrypted to a content key, and the content associated with policy information is decrypted using the content key and at least one additional factor, which defines additional content protection beyond that provided by trusted agent.
Patent
Method, apparatus and system for use in distributed and parallel decryption
TL;DR: In this paper, 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 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 instances key at the second system independent of the first one, decrypts the encrypted content keys using the generated first instance keys at the other system; and decrypts a first encrypted key using the first unencrypted content
