“…This observation verifies the explanations presented in Ref. [22] that SEFA works more effectively in the presence of noise since the probability distribution of effective fault becomes more biased.…”

“…They complement one other by exploiting fault inductions that are either ineffective (SIFA) or effective (SEFA). Statistical effective fault attack is a further attack that employs correct ciphertexts corresponding to the effective faults [22]. Statistical ineffective fault attack and SEFA both take advantage of the fact that the distribution of an intermediate value among a set of ciphertexts can be non‐uniform.…”

“…Vafaei et al. recently developed another statistical fault attack as an alternative to SIFA, which exploits effective faults rather than ineffective ones [22]. The fact that Statistical Effective Fault Attack (SEFA) performs better than SIFA in some critical scenarios motivates us to take it a step further and develop the blind SEFA presented in this study so that we can benefit from both being blind and combining them in this newly presented attack strategy.…”

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