Computing device with a manipulation detection and a method for detecting a manipulation of a computing device

摘要

The manipulation device (10) with a manipulation recognition provides services with real-time requirements by means of a program code (15) and comprises at least one processor unit (11) and a monitoring unit (12). The processor unit (11) is designed to execute the program code (15). The monitoring unit (12) is designed to determine and store a reference runtime spectrum (16) for the program code (15) in a recording phase by executing a multiplicity of possible variants of the program code (15) and determining a runtime for each variant or saved. Subsequently, in a monitoring phase, the running time of the execution of the program code (15) is continuously determined, the determined runtime compared with the reference runtime spectrum (16) and generates a warning if the determined runtime does not coincide with any runtime included in the reference runtime spectrum. The method according to the invention comprises corresponding method steps.
