All KEM schemes use variants of the Fujisaki-Okamoto transformation, so the equality test with re-encryption in decapsulation is critical..We survey effective key-recovery attacks when we can skip the equality test. We found the existing key-recovery attacks against Kyber,

It has already been shown that a straightforward combination of SCA and FA countermeasures are vulnerable against FAs, such as Statistical Ineffective Fault Analysis (SIFA) and Fault Template Attacks (FTA). Consequently, new classes of countermeasures have been proposed which prevent

In this paper, we first present a leakage-resilient MAC that is both efficient and secure under standard and easily interpretable black box and physical assumptions. It only requires a collision resistant hash functio
