A method is provided for executing a code sequence on a security module. The code sequence comprises codes to be replaced and codes to be interpreted. A temporary replacement takes place of a respective code to be replaced by a partial code sequence that comprises at least one code having an interpretable code value. The replacement taking place is dependent on the code value of the code to be replaced. An interpretation of the codes to be interpreted in the code sequence and in the partial code sequence takes place with the aid of interpretation information for code values. During the replacement step, the partial code sequence for the code value of the code to be replaced is additionally produced in dependence on a piece of selection information.
