Exploiting statistical effective fault attack in a blind setting

In order to obtain the secret key, majority of physical attacks require knowledge plaintext or ciphertext, which may be unavailable cannot exploited. Blind are introduced do key recovery in circumstances where adversary has no direct access and ciphertext. A combination fault power can circumvent typical countermeasures this setting, for example, Fault Template Attack (FTA). However, FTA relies on bit injection, is difficult implement practice. The SIFA-blind, a framework executing Statistical Ineffective Attack, more flexible, but sensitivity setup noise missed faults its main drawback. To address deficiency, we suggest two ways use Effective blind setting that much less affected by when measuring traces, even though they not injection at level. demonstrate viability adaptability our proposed attacks, injected via glitch frequency onto ChipWhisperer board. While SEFA-blind does need bit-level fault, results it better than SIFA-blind number increases.
