Abstract

L'invention concerne un procédé et un appareil de transmission de données, ainsi qu'un terminal. Le procédé comprend les étapes suivantes : un premier terminal reçoit une instruction de transmission de données pour indiquer une transmission de données cibles à un second terminal ; le premier terminal détermine une valeur d'importance des données cibles ; là où la valeur d'importance des données cibles est supérieure à une valeur seuil prédéfinie, le premier terminal utilise une clé pour chiffrer les données cibles et obtient des données chiffrées ; et le premier terminal envoie les données chiffrées au second terminal en réponse à l'instruction de transmission de données. La mise en œuvre des modes de réalisation de la présente invention peut améliorer la sécurité de la transmission des données.
