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： 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 “follow-me” utility runs on each of a plurality devices a person may typically use. This utility monitors applications running on a device and intelligently saves the state of tasks a user is performing. When the follow-me utility detects that the user has initialized another device having the follow-me utility and connectivity to the original device, the utility automatically and transparently creates an environment on the new device so that the user may continue the task at the same point as when he or she last performed the task on the original device. When the user continues a task or starts a new task, the follow-me utility automatically and transparently updates files and task states on any devices having the follow-me utility and connectivity. The follow-me utility may make intelligent task migration decisions based on conditions such as network bandwidth, security policy, location, and device capability.

摘要： A system and method for maintaining data coherency in a system in which data is replicated on two or more servers. Each server is able to update the data replica present on the server. Updates are logged for each server. Reconciliation of server data replicas is aggressively initiated upon the occurrence of predefined events. These events include arrival at a scheduled time, a request for data by a client system, server and network failure recovery. Reconciliation is managed by a coordinator server selected to ensure that at most one coordinator server per network partition is selected. Logged updates are merged and transmitted to each server containing a data replica. The logged updates are applied unless a conflict is detected. Conflicts are collected and distributed for resolution. Reconciliation is managed between servers without regard to operating system or physical file system type.

摘要： A method and system is presented for configuring a group of OCSP (Online Certificate Status Protocol) responders so that they are highly available. Each of the grouped OCSP responders share a common public key. When responding to an OCSP request, an OCSP responder generates an OCSP response that is signed with a group digital signature; the certificate for the common or group public key can be attached to the OCSP response. An OCSP client uses the group public key to verify the group digital signature on an OCSP response from any of the OCSP responders. For an OCSP client, the availability of this group of responders is greater than the availability of any one member of the group.
