Abstract: To easily identify an invalid device certificate by means of a validity check when signing keys that are used to create device certificates are compromised, a piece of status information is provided for device certificates that comprises positive evidence of the existence and validity of the device certificate, and alternatively or additionally to apply a special validity model for device certificates, wherein the time of issue of the device certificate is documented by means of a signed electronic timestamp, and wherein a different signing key is used for signing the timestamp than for signing the device certificate. Additionally, all information that is required for the validity check of a device certificate is stored in a memory of the device or in a memory associated with the device, so that an identity check on the device can be performed at any time without fetching additional data.

Abstract: Embodiments involve a data organization procedure and a development environment system that is set up to carry out the data organization procedure. The data organization procedure according to an embodiment envisages that a stored data set or a data set to be stored is organized according to a first structure, whereby the data set is subdivided according to aspects of the content and/or according to access rights aspects into partial data sets, whereby in addition to the first structure another structure is envisaged, according to which the data set is organized, whereby the data set is subdivided into authority areas, whereby each authority area includes at least one partial data set according to the first structure, whereby each partial data set includes at least one data unit, and whereby a responsible user set is allocated to each authority area, whereby the user set includes at least one user.

Abstract: A wheel carrier for motor vehicles with a slotted area. The wheel carrier has two limitedly elastic clamping jaws on a wheel side, which are traversed by a clamping bolt, whose tightening torque determines the strength of a clamping joint. This clamping joint fixes an end piece of a pivot pin of a ball-and-socket joint, especially a guiding joint. This end piece is inserted into the wheel carrier. The joint ball of the pivot pin is mounted in a housing accommodating the joint ball movably in all directions. A clamping protector 5 covering the slotted area 1.1 of the wheel carrier 1 is inserted into the slotted area 1.1 of the wheel carrier 1 and is sealingly fixed in the slotted area, while the material of the clamping protector undergoes plastic deformation in at least some areas.
