Abstract: A method is for protecting a program code that is executed by a computer processing module having a central processing unit coupled to a cache memory containing cache lines that each have a data field that is intended to store instruction words that can be executed by the central processing unit. The method includes storing the program code in memory locations of an external memory with respect to the computer processing module, each memory location being capable of storing the instruction words of one cache line. The method also includes determining authentication codes that are respectively associated with the cache lines and, for each cache line, fragmenting the associated authentication code and storing this distributed fragmented authentication code in the corresponding memory location.
