摘要
A method for hardening the Stack-Smashing Protector (SSP) technique which prevents information leaking of the protecting guard is disclosed. The reference stack guard secret value is renewed at one or more selected time points during the execution of the application. The technique is non-intrusive and has a negligible run-time cost (both spatial and temporal). The technique reuses the SSP infrastructure, and does not need to recompile the code or modify the binary image of the application. The method prevents any kind of brute force attacks against the SSP technique and most memory leaks affecting the canary guard.
