Abstract:

Control flow integrity (CFI) restricts jumps and branches within a program to prevent attackers from executing arbitrary code in vulnerable programs. However, traditional CFI still offers attackers too much freedom to chose between valid jump targets, as seen in recent attacks. We present a new approach to CFI based on cryptographic messa...More
