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： Enhanced configuration of security and access control for data in a storage device is disclosed. A request is received to access an addressable memory location in a storage media within the storage device. A set of addressable memory locations with contiguous addresses identified by an address range is associated with first and second characteristics. The first characteristic is applied if the addressable memory location is within the set of addressable memory locations, and an entity is currently authenticated to and authorized to access the set of addressable memory locations. The second characteristic is applied if the addressable memory location is within the set of addressable memory locations, and no entity is currently authenticated to and authorized to access the set of addressable memory locations. The set of addressable memory locations can also be a logical partition, where the first and second characteristics are stored in a logical partition table.

摘要： Host devices present both the host certificate and the pertinent certificate revocation lists to the memory device for authentication so that the memory device need not obtain the list on its own. Processing of the certificate revocation list and searching for the certificate identification may be performed concurrently by the memory device. The certificate revocation list for authenticating a host device to a memory device is cached and current prior to the memory device receiving the host certificate.

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： The embodiments described herein provide methods for producing products with certificates and keys. In one embodiment, a requesting entity transmits a request for a plurality of certificates and corresponding keys to a certifying entity that generates the certificates and corresponding keys. The request preferably includes information for use by the certifying entity to verify an identity of the requesting entity rather than information to verify unique product identifiers of the respective products. The requesting entity then receives the plurality of certificates and corresponding keys from the certifying entity, preferably in a plurality of organized sets instead of in a single series of certificates. The requesting entity then stores the certificates and corresponding keys in respective products. Each stored certificate is thereafter useable for both identification and authentication of the respective product in which it is stored.
摘要翻译：本文所述的实施例提供了用证书和密钥生产产品的方法。在一个实施例中，请求实体向生成证书和对应密钥的认证实体发送对多个证书和对应密钥的请求。该请求优选地包括由认证实体用于验证请求实体的身份而不是用于验证相应产品的唯一商品标识符的信息的信息。然后，请求实体从认证实体接收多个证书和对应的密钥，优选以多个有组织的集合而不是一系列证书中的密钥。然后，请求实体将证书和对应的密钥存储在相应的产品中。每个存储的证书此后可用于其存储的相应产品的识别和认证。
