Defeating Low-Cost Countermeasures against Side-Channel Attacks in Lattice-based Encryption
In an effort to circumvent the high cost of standard countermeasures against side-channel attacks in post-quantum cryptography, some works have developed low-cost detection-based countermeasures.These countermeasures try to detect maliciously generated input ciphertexts and react to them by discarding the ciphertext or secret key.In this work, we t
