Résumé
Dans cet article, nous avons proposé un système de cryptage des signaux vocaux basé sur des décalages circulaires en ligne et en colonne. Ce cryptosystème utilise trois clés secrètes. La clé originale est générée de manière aléatoire à l'aide d'un générateur de séquence de pseudo-bruit, et les deux autres clés sont obtenues en utilisant la clé principale. Le système de cryptage utilise également la transformation cosinus discrète (DCT) ou la transformation sinusoïdale discrète (DST) pour supprimer l'intelligibilité du signal. De plus, les performances de l'algorithme proposé sont également estimées par la quantité de coefficient de corrélation.
