Method and computer system for protecting a computer program against influence

Method for protecting a computer program against the influence of an intrusive program or manipulation software used to manipulate computer programs on a computer system with a processor unit, main memory, and a storage medium. The method relies on Kerckhoffs’ Principle. Parts of the computer program are encrypted to prevent its static analysis without execution of the program by the processor. A key required for decrypting the encrypted parts of the computer program is stored in a secure container that communicates with the computer.
