摘要：
A method for executing a binary code of a secure function includes obtaining a pointer containing: a first range of bits containing the address of a line of code, and a second, different range of bits containing an identifier of the pointer, storing the line of code, this line of code containing a first integrity tag constructed or encrypted using the identifier of the pointer, loading the line of code from the address contained in the first range of bits of the pointer, verifying the integrity of the loaded line of code by constructing a second integrity tag using the identifier of the pointer contained in the second range of bits of the pointer used to load it.
