Abstract

L'invention concerne un procédé et un dispositif de chiffrement d'informations, un procédé et un dispositif de déchiffrement d'informations, et un terminal. Le procédé de chiffrement d'informations comprend les étapes suivantes : lorsqu'une opération d'envoi d'informations de communication instantanée à un terminal de réception cible est détectée, chiffrer les informations de communication instantanée de façon à obtenir un paquet de données de texte chiffré, le paquet de données de texte chiffré comprenant des nombres aléatoires utilisés pour l'opération de chiffrement, et des données de texte chiffré obtenues par l'intermédiaire de l'opération de chiffrement (102) ; et envoyer le paquet de données de texte chiffré au terminal de réception cible (104). Au moyen de la solution technique, des informations de communication instantanée peuvent être transmises après un chiffrement, de telle sorte qu'il est difficile pour d'autres de voler des informations pertinentes, ce qui permet d'assurer la sécurité de transmission des informations de communication instantanée et de garantir efficacement la confidentialité d'un utilisateur.
