Abstract: The present invention provides a method, system and program product for modifying content usage conditions during broadcast content distribution. Specifically, the present invention allows protected (e.g., encrypted, secured, etc.) content to be received along with content usage conditions, an encrypted combination of the content usage conditions and a title key (e.g., a MAC), and a key management block. Using the key management block, a key encrypting key can be determined for decrypting the combination. Once the combination is decrypted, the content usage conditions can be modified (e.g., edited, added to, etc.).

Abstract: A tree is used to partition stateless receivers in a broadcast content encryption system into subsets. Two different methods of partitioning are disclosed. When a set of revoked receivers is identified, the revoked receivers define a relatively small cover of the non-revoked receivers by disjoint subsets. Subset keys associated with the subsets are then used to encrypt a session key that in turn is used to encrypt the broadcast content. Only non-revoked receivers can decrypt the session key and, hence, the content.

Abstract translation: 一棵树用于将广播内容加密系统中的无状态接收器分成子集。 公开了两种不同的分割方法。 当识别出一组撤销的接收者时，撤销的接收者通过不相交的子集定义非撤销的接收者的相对较小的覆盖。 与子集相关联的子集密钥然后用于加密会话密钥，会话密钥又用于加密广播内容。 只有非撤销的接收者可以解密会话密钥，因此可以解密内容。
