Microcontroller and assigned method for processing the programming of the micro-con- troller

Abstract

In order to further develop a microcontroller (100) the programming of which is carried out in at least one machine-dependent assembler language in which the assembler commands, with the exception of conditional program jumps or branches, can be executed in essence independently of data, together with a method for processing the programming of the microcontroller (100) carried out in at least one machine-dependent assembler language, in such a way that the program running on the microcontroller (100) is entirely secret and unpredictable, i.e. is not reproducible, for an external observer, it is proposed that the program jumps or branches are executed—in dependence on the state of at least one random number generator (10) and/or—independently of the internal state of the programming of the microcontroller (100).

Dependencies are inferred from the claim text.
