Abstract
A method for executing a computer program includes incorporating, into metadata of a block containing a line of code to be accessed using a pointer, a first pointer identifier associated with the line of code to be accessed, then obtaining a pointer including a first range of bits containing the address of the line of code to be accessed, and a different second range of bits containing a second pointer identifier, then verifying that the second pointer identifier contained in the obtained pointer corresponds to the first pointer identifier associated with the line of code to be accessed and contained in the metadata of the loaded block, and when the first and second pointer identifiers do not correspond, then the security module triggers signaling of an execution fault.
