    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。

    Abstract: A method of implementing a full coverage low power mode in a storage system comprised of one or more memory storage devices storing replicated data items. A subset of the memory storage devices is chosen whose replicated data items require the least amount of storage. If the chosen subset stores uncovered data items, these data items are copied to an auxiliary memory storage device. The storage system can enter a full coverage low power mode by powering down the chosen subset of memory storage devices.

    Abstract translation: 一种在由存储复制数据项的一个或多个存储器设备组成的存储系统中实现全覆盖低功率模式的方法。 选择存储器存储设备的子集，其复制数据项需要最少量的存储。 如果所选择的子集存储未覆盖的数据项，则这些数据项被复制到辅助存储器存储设备。 存储系统可以通过关闭所选择的存储器存储设备的子集来进入全覆盖低功率模式。

    Abstract: A method for accessing a storage device, the method includes: receiving, by storage device, a block based storage access command and cryptographically secured access control information; wherein the block based storage access command and the cryptographically secured access control information are associated with at least one fixed size block of data and with a client; processing at least a portion of the cryptographically secured access control information by using a secret key accessible to the storage device and to a security entity; and selectively executing the block based storage access command in response to a result of the processing.

    Abstract: A method for tracing traitor receivers in a broadcast encryption system. The method includes using a false key to encode plural subsets representing receivers in the system. The subsets are derived from a tree using a Subset-Cover system, and the traitor receiver is associated with one or more compromised keys that have been obtained by a potentially cloned pirate receiver. Using a clone of the pirate receiver, the identity of the traitor receiver is determined, or the pirate receiver clones are rendered useless for decrypting data using the compromised key by generating an appropriate set of subsets.
