Abstract

The invention relates to a method for protecting a computer program from being influenced by an invasive program or by manipulation software for manipulating computer programs on a computer system comprising a processor, a main storage unit, and a storage medium. The method involves the Kerckhoffs's principle such that the protected computer program is freely accessible and can be read by an invasive program or manipulation software. Parts of the protected computer program are provided multiple times in the program code of the protected computer program as a result of the specialization of the computer program. Parts of the computer program are encrypted in order to prevent a statistical analysis of the computer program without the processor running the computer program, wherein a key which is required to decrypt the encrypted parts of the computer program is stored in a protected key storage unit which communicates with the computer.
