Analyse de consommation (cryptographie)

En cryptanalyse de matériel cryptographique, l'analyse de consommation consiste à étudier les courants et tensions entrants et sortants d'un circuit dans le but de découvrir des informations secrètes comme la clé de chiffrement. Certaines opérations, plus coûteuses, augmentent la consommation électrique du circuit, notamment par l'utilisation de plus de composants (analogiques ou logiques). Cette analyse des variations et des pics permet de tirer des informations précieuses pour le cryptanalyste.
