Abstract: Provided are a system and a method for secure access to data, where the data comprises a number of data records each assigned to an entity, such as a user, and where the data records are stored in encrypted form in a database. A first decryption key assigned to a particular entity is used to decrypt the data records assigned to the particular entity. The first decryption keys are stored in a volatile memory, and the first decryption keys assigned to the particular entity are encrypted by an encryption key assigned to the particular entity, and the encrypted first decryption keys are stored in a permanent memory. After the volatile memory is cleared, the encrypted first decryption keys are copied from the permanent memory into the volatile memory, and in the volatile memory, the first decryption keys are decrypted by a second decryption key assigned to the particular entity.

Abstract: A method is provided for securely and efficiently accessing connection data of at least one telecommunication provider is provided, wherein the connection data is ascertained by the telecommunication provider and is encrypted by the telecommunication provider, the encrypted connection data is transmitted from the telecommunication provider to a secured environment, the connection data is decrypted in the secured environment and, for a first predetermined time period, is stored as decrypted connection data exclusively in a volatile memory of the secured environment, and the access to the connection data is exclusively granted as access to the decrypted connection data stored in the volatile memory of the secured environment via a predetermined interface of the secured environment.

Abstract: An ad hoc network is formed as a connection between a local area network with its services and at least one body-worn network when at least one computer in the local area network detects the local services located in the local area network, translates them into Jini services and offers them on the IP plane with the use of Jini middleware for body-worn networks.

Abstract: In a network, in particular an ad-hoc network AHN, having a blackboard on which all the usable services are entered, following detection of a service which has not yet been entered on the blackboard, a check is carried out to determine whether use of the service is admissible. The service is entered onto the blackboard only if use of the service is admissible. This provides centrally administrable secure use of services in plug & play networks.

Abstract: A layer of network elements is provided between already existing physical networks and service providers or users. The network elements communicate via interfaces not only with each other, but also with the physical networks which are connected to them. This layer, which is implemented by network elements distributed in the network, enables the network user to access the existing network resources available in the physical, subjacent networks. This enables all available basic and value-added services to be used. The required and generated data are collected separately according to users or service providers in the relevant physical networks, and are managed and made available for further processing.

Abstract: A hardware module for incorporating an electronic unit into an ad-hoc network has a unit to operate a Java virtual machine which supports Java RMI and Jini. The hardware module has at least one interface to a communications interface on the electronic unit. Jini services are generated with interface stubs for the hardware of the electronic unit. The hardware module has at least one interface to a local area network.

Abstract: A server rack for holding a plurality of computer systems. In order to prevent the complex detachment of the cabling at the back when changing, maintaining or upgrading the individual computer systems, the server rack has a plugin apparatus (1) into which holding adapters (2) can be plugged which, in turn, can each hold a computer system. The consecutive slot numbers in the plugin apparatus are made available to the fitted computer systems as a location identifier.

Abstract: A distributed operating system for controlling network elements in a data or telecommunication network in which the operating system controls a data and communication network consisting of various underlying physical base networks. These base networks consist of network elements that provide various network (basic) services and network functions and can be controlled by system-specific calls. Accordingly, there exist higher-ranking network elements that are equipped with specific operating system components and execute basic functions independent of the physical subnetworks, such as accessing the physical base networks, distributing the calls of basic services, and converting the calls into the corresponding system-specific formats.

Abstract: A method and system for the secure use of a service, wherein the use software for a service is extended by at least one security function to form at least partially secure use software. The service is used using the extended use software. This provides secure use RMI of services, preferably in plug & play networks.

Abstract: The arrangement connects at least one module (M) to a power supply unit (SV) in an apparatus in such a way that a connection is provided when the power supply unit (SV) is switched on. In the apparatus is a contact element (KG, VE) which is located outside the module and has leading contacts and a device for current limitation (AS) of an initial current flow.

Abstract: A process for flexible rate charging for existing connections permits flexible rate charging for services delivered through telecommunication networks. A variable price agreement is accomplished between a service provider and a service user within a predetermined framework, and adherence thereto is checked through the use of an independent verification system.

Abstract: An arrangement of an isolating support board having conductive surfaces between busbars, the support board having a portion projecting beyond the busbars in the transverse direction, and filter capacitors connected to the conductive surfaces being fastened on the projecting portion.
