摘要： A memory device for using time from a trusted host device and a method for use therewith are disclosed. In one embodiment, an application on a memory device receives a request to perform a time-based operation from an entity authenticated by the memory device, wherein the entity is running on a host device. The application selects time from the host device instead of time from a time module on the memory device to perform the time-based operation and uses the time from the host device to perform the time-based operation. Other embodiments are disclosed, and each of the embodiments can be used alone or together in combination.

摘要： A memory device with circuitry for improving accuracy of a time estimate used in digital rights management (DRM) license validation and a method for use therewith are disclosed. In one embodiment, a memory device receives a request to validate a DRM license stored on the memory device, wherein the DRM license is associated with a time stamp update policy (TUP) that specifies when a new time stamp is needed. Before attempting to validate the DRM license, the memory device determines if a new time stamp is needed based on the TUP associated with the DRM license. If a new time stamp is needed, the memory device receives the new time stamp and then attempts to validate the DRM license using a time estimate based on the new time stamp. Other embodiments are disclosed, and each of the embodiments can be used alone or together in combination.

摘要： A memory device with circuitry for improving accuracy of a time estimate and a method for use therewith are disclosed. In one embodiment, a memory device receives a time stamp and measures active time with respect to the received time stamp. The memory device determines accuracy of previously-measured active time and generates a time estimate using the measured active time, the accuracy of previously-measured active time, and the received time stamp. In another embodiment, measured active time is adjusted, with or without generating a time estimate. Other embodiments are disclosed, and each of the embodiments can be used alone or together in combination.

摘要： A memory storing public and confidential information is removably connected to a host device. General information on data stored in memory devices is accessible to the host device without authentication. Only a portion of confidential information stored in the memory device is accessible through the host device to an authenticated entity, where the entity has access rights to such portion. The entity is not able to access other portions of confidential information to which it has no rights. The public and confidential information is stored in a non-volatile storage medium, and a controller controls the supply of information. Preferably, the non-volatile storage medium and the controller are enclosed in a housing.

摘要： The mobile storage device may be provided with a system agent that is able to create at least one hierarchical tree comprising nodes at different levels for controlling access to data stored in the memory by corresponding entities. Each node of the tree specifies permission or permissions of a corresponding entity or entities for accessing memory data. The permission or permissions at the node of each of the trees has a predetermined relationship to permission or permissions at nodes at a higher or lower or the same level in the same tree. Thus, the mobile storage devices may be issued without any trees already created so that the purchaser of the devices has a free hand in creating hierarchical trees adapted to the applications the purchaser has in mind. Alternatively, the mobile storage devices may also be issued with the trees already created so that a purchaser does not have to go through the trouble of creating the trees. In both situations, preferably certain functionalities of the trees can become fixed after the devices are made so that they cannot be further changed or altered. This provides greater control over access to the content in the device by the content owner. Thus, in one embodiment, the system agent can preferably be disabled so that no additional trees can be created.
摘要翻译：移动存储设备可以被提供有能够创建包括不同级别的节点的至少一个分级树的系统代理，用于控制对相应实体存储在存储器中的数据的访问。树的每个节点指定用于访问存储器数据的相应实体或实体的许可或许可。每个树的节点的权限或权限与同一树中较高或较低或相同级别的节点处的许可或许可具有预定关系。因此，移动存储设备可以在没有任何已经创建的树的情况下被发布，使得设备的购买者可以自由地创建适应购买者所考虑的应用的分层树。或者，移动存储设备也可以被发布已经创建的树，使得购买者不必经历创建树的麻烦。在这两种情况下，优选地，在制造装置之后，树的某些功能可以变得固定，使得它们不能被进一步改变或改变。这可以更好地控制内容所有者对设备内容的访问。因此，在一个实施例中，系统代理可以优选地被禁用，使得不能创建额外的树。

摘要： A method and memory device for implementing long operations and supporting multiple streams are provided. In one embodiment, a memory device receives data and a command from a host to perform an operation on the data, wherein a time required for the memory device to complete the operation exceeds a maximum response time for the memory device to respond to the command. The memory device begins performing the operation on the data and, before exceeding the maximum response time and before completing the operation, sends the context of the operation to the host. At a later time, the memory device receives from the host: (i) a command to resume performing the operation and (ii) the context. The memory device then resumes performing the operation on the data based on the context received from the host.

摘要： An object known as an identity object comprises a public key and a private key pair and at least one certificate issued by a certificate authority that certifies that the public key of the pair is genuine. This object may be used as proof of identification by using the private key to sign data provided to it or signals derived from the data. An identity object may be stored in a non-volatile memory as proof of identity. The memory is controlled by a controller. Preferably, a housing encloses the memory and the controller. The memory system is removably connected to a host device. After the host device has been successfully authenticated, the private key of the object is used to encrypt data from the host device or signals derived from said data, and the at least one certificate and the encrypted data or signals are sent to the host device. After an entity has been authenticated by a control data structure of the memory system, the public key of the identity object and the at least one certificate to certify the public key are provided to the entity. If encrypted data encrypted by means of the public key of the identity object is received from the entity, the memory system will then be able to decrypt the encrypted data using the private key in the identity object.
