The invention generally relates to management of cryptographic key generations in an information environment comprising a key-producing side generating and distributing key information to a key-consuming side. A basic concept of the invention is to define, by means of a predetermined one-way key derivation function, a relationship between generations of keys such that earlier generations of keys efficiently may be derived from later ones but not the other way around. A basic idea according to the invention is therefore to replace, at key update, key information of an older key generation by the key information of the new key generation on the key-consuming side. Whenever necessary, the key-consuming side iteratively applies the predetermined one-way key derivation function to derive key information of at least one older key generation from the key information of the new key generation. In this way, storage requirements on the key-consuming side can be significantly reduced.

In a conventional managed information environment network, event notification mechanisms typically monitor the various nodes and interconnections in the network. In particular configurations of the invention, an event service infrastructure allows an event, or class definition, to define the event and related event data. Invocation of the event includes only the event specific class definition. The infrastructure transparently processes the subsequent reporting and invocation of the appropriate event handler. The event handler, corresponding to the event definition, performs remedial and responsive processing of the event. A developer need only develop entities to subscribe to an event to identify the appropriate handler, and publish the event with any related event data upon detection. Each particular event avoids extraneous event definitions and associated files, thereby relieving the developer from unrelated events and allowing focus on the pertinent events. A detecting software entity initiates event handling by publishing the event, upon which the event service identifies and invokes each subscriber entity for performing the event handler associated with the event.

Although recording of usage data is common in scholarly information services, its exploitation for the creation of value-added services remains limited due to concerns regarding, among others, user privacy, data validity, and the lack of accepted standards for the representation, sharing and aggregation of usage data. A technical, standards-based architecture for sharing usage information is presented. In this architecture, OpenURL-compliant linking servers aggregate usage information of a specific user community as it navigates the distributed information environment that it has access to. This usage information is made OAI-PMH harvestable so that usage information exposed by many linking servers can be aggregated to facilitate the creation of value-added services with a reach beyond that of a single community or a single information service.

A custom host naming mechanism that allows a user to define a custom host name as a virtual name for the hosts in the managed information environment, such as the storage area network, overcomes the shortcomings of the use of a network assigned machine name during a failover operation. The custom host naming mechanism allows the operator to define a mnemonic virtual name for each host in the managed information environment, thereby facilitating failover switching. Further, such secondary hosts may undertake offline, lower priority executing tasks while not in failover mode, and rapidly reconfigure as the failover secondary host should the need arise. Therefore, secondary hosts at a hot site deploy with a mnemonically descriptive name indicative of their status as a secondary host for a corresponding primary host, and further, need not remain idle pending a disaster recovery scenario, but rather are employable for offloading of other, lower priority tasks pending failover response.
