摘要： Use of cryptographic key-store hardware security modules is optimized in a system having a first scarce high-security key storage device and a second more plentiful low-security key storage device comprising securing a cryptographic key to the higher security level by initially storing the key in the first storage device, then responsive to an event, evaluating the stored key against one or more rules, and subsequent to the evaluation, reclassifying the stored key for relocation, encrypting the reclassified key using a key-encryption key; relocating the reclassified key into the second, lower-security storage device, and storing the key-encryption key in the first storage device.

摘要： A method, a data processing system, and a computer program product for managing cryptographic information. A determination is made as to whether a first time stamp of when cryptographic information was created is more recent than a second time stamp of a backup of the cryptographic information in response to receiving a request for the cryptographic information from a requester. The cryptographic information is used to encrypt data. The cryptographic information is prevented from being provided to the requester in response to a determination that the first time stamp of cryptographic information creation is more recent than the second time stamp of the backup of the cryptographic information.

摘要： A method is presented for processing data in a multithreaded application to alleviate impaired or substandard performance conditions. Work items that are pending processing by the multithreaded application are placed into a data structure. The work items are processed by a plurality of threads within the multithreaded application in accordance with a first algorithm, e.g., first-in first-out (FIFO). A thread within the multithreaded application is configured apart from the plurality of threads such that it processes work items in accordance with a second algorithm that differs from the first algorithm, thereby avoiding the impairing condition. For example, the thread may process a pending work item only if it has a particular characteristic. The thread restricts its own processing of work items by intermittently evaluating workflow conditions for the plurality of threads; if the workflow conditions improve or are unimpaired, then the thread does not process any work items.
