Abstract

Techniques for enforcing flow control of a software program in a processor are provided. An example method according to these techniques includes analyzing program code of the software program to identify a code pointer in the program code, generating an authentication tag based on the code pointer, and modifying the code pointer in the program code with the authentication tag to generate a tagged code pointer.
