You want to know at the pre-silicon stage whether your device is going to pass the TVLA test or not. This is especially critical if you are going for NIST certification. Check out this video to explore the test methodology adopted by NIST as part of their new certification standard. You’ll discover that the basic idea of TVLA is to perform two experiments on your device and then to compare the results using standard statistical methods. If there is a significant difference between the results of the two experiments, it indicates that there’s a high possibility for an attacker to gain access to your secret key by analyzing these differences.
