Get the serial ARM CPU information with a C/C++ program

I can get the serial ARM CPU (Raspberry Pi) information with a C/C++ program. I could get this information from /proc/cpuinfo but then it is very easy to hack the program. Does anyone know how can the serial number obtained through C/C++? I want to use the serial number for cryptographic operations.

This one is easy: Start with fd=fopen("/proc/cpuinfo", "r");

What I ofcourse mean, that to distrust /proc/cpuinfo means to distrust the running kernel - under this premise, all bets are off.
