An instruction block (IB) is provided on the basis of at least a portion (MC-P) of the program. A protective code (DS) is generated that has a predefined relationship with the instruction block (IB). The instruction block (IB) is analyzed (ANL) so as to identify free ranges (FI) within the instruction block that are neutral with respect to an execution of the instruction block. The free ranges comprise at least one of the following types: bit ranges and value ranges. The free ranges that have been identified are used for embedding (SEB) the protective code (DS) within the instruction block (IB).
