Zusammenfassung:A method for an automated protection of a programmable code and data without using dedicated components for calculation of the checksums and/or hash values is provided. Execution of each machine instruction uses data from several small blocks of protected code or data. Each of the blocks can be used in forming several machine instructions. If an intruder changes even one of the code blocks or data, it results in incorrect decoding of several machine instructions. Thus, the entire application does not work correctly. The intruder cannot neutralize a code protection mechanism.
