Abstract: A method for the administration of resources, in which classes or instances, respectively, are assigned to the resources and a program receives a rule assigned to the class or instance, respectively, and applies it to the resource. It is made sure that only rules assigned to the class or instance, respectively, are applied on the resource. In alternative methods, only rules are applied on the resource, which were accepted by a verification rule assigned to the resource.

Abstract: Method for processing data, in which a Petri net is encoded, written into a memory and read and excuted by at least one instance, wherein transitions of the Petri net read from at least one tape and/or write on at least one tape symbols or symbol strings, with the aid of at least one head. [FIG. 1]. In an alternative, data-processing, co-operating nets are composed, the composition result is encoded, written into a memory and read and executed from the memory by at least one instance. In doing this, components can have cryptological functions. The data-processing nets can receive and process second data from a cryptological function which is executed in a protected manner. The invention enables processing of data which prevents semantic analysis of laid-open, possibly few processing steps and which can produce a linkage of the processing steps with a hardware which is difficult to isolate.
