A system for provisioning service environments (SEs) and resources includes a component for creating and handling state change events and a parts catalog including descriptions of SEs, variable federated resources, aggregated, and basic resources. The system further includes a planner component for generating plans for construction and destruction of SEs and plans for creation, addition, removal and destruction of every aggregated resource to or from the SEs. The planner component has an interface to the parts catalog and an interface to a global dynamic free pool manager. The global dynamic free pool manager is configured for dynamically constructing and destructing dynamic free pool managers with their assigned dynamic free pools including dynamically changing their capacities.

System, method and computer program product for provisioning of resources and service environments

The present invention provides a system, method, and computer program product to accelerate provisioning by dynamically creating dynamic free pools (DFPs) of pre-provisioned resources that are provisioned in advance, and are ready and free for use. A DFP construct for a resource, and its associated dynamic free pool manager are generated dynamically from a formal description of an aggregated resource structure (e.g. in the form of an XML schema). The present invention also provides a system, method, and computer program product to improve the delivery time of SEs based on the DFP constructs. The methods are extended to deal with special conditions such as contention over resources, or critical delivery time.

The invention relates to the generation of digital signatures by the use of which the legally binding nature of a digital signature is enhanced. For this, an expanded digital signature is created which, in addition to the hash, contains other information, in particular information identifying the hardware and software environment used in generating the signature.

Digital signature

A method for creating, storing and reading a new certificate type for certification of keys is provided. In the new certificate type, several certificates, containing a minimum quantity of redundant data fields, are collated to form one certificate and all redundant information on the certificates is eliminated. An embodiment of the new certificate type is the group certificate. The group certificate is used where several keys are to be issued at the same time for the same user by the same certification instance. By means of the group certificate, all redundant data elements are eliminated and all data elements for a set of several keys subject to certification are grouped into one certificate. This substantially reduces the memory requirement, and handling of the certificates is simplified for the communication partners. A further embodiment of the new certificate type is the basic and supplementary certificate combination. This form of certification is used where certificates are issued at different times for the same user by the same certification body. The memory requirement is consequently somewhat more than for group certificates, but greater flexibility is gained in use of the keys.
