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.
