Compiler - system and method for compiling of a said source code to form an encrypted machines of a speech code

摘要

Processing unit (20) for carrying out a maschinensprachcades (15), has the following features:a register for a program counter (70);an embodiment of a circuit arrangement (75);a retrieval means (60), which is configured, a word of an address of a with the processing unit (20) can be connected with the program memory (30) to call up, wherein the address of a current state of the program counter (70) and the program counter (70) is configured to a call to be incremented towards;a decryption unit (40), which is configured, one of the program memory (30) retrieved and received encrypted instruction of the machines of a speech codes through a decrypting function, which depends from the value of the program counter, to decrypt,the decrypted machines of a speech code useful data, which in the embodiment a behavior of the processing unit, and error detection of data which include a testing a integrity of the useful data and of no importance with respect to the behavior of the processing unit are;a fault detection of a unit (99), which is configured to set the fault detection data of the decrypted machines of a speech code with the expected error detection data can be compared, in order to detect an error or a forced engagement of an enemy attacker to the processing unit to detect.
