Abstract

L'invention porte sur un procédé d'écriture de clé de cryptage et sur un terminal mobile. Le procédé consiste : lors de la détection d'un premier démarrage d'un système actuellement installé dans un terminal mobile, à acquérir un paquet de données poussé par un serveur, le paquet de données comprenant un programme d'écriture de clé de cryptage ; à extraire le programme d'écriture de clé de cryptage du paquet de données, le programme d'écriture de clé de cryptage comportant une clé de cryptage ; à exécuter le programme d'écriture de clé de cryptage pour écrire la clé de cryptage dans une région de stockage cryptée du terminal mobile, la clé de cryptage étant utilisée pour crypter un type préétabli de données.
