Abstract

L'invention porte sur un procédé d'obtention d'un code de déverrouillage, et sur un terminal mobile. Le procédé comprend les opérations suivantes : un terminal mobile envoie son propre code caractéristique à un serveur de réseau après avoir déterminé qu'une condition de déverrouillage préréglée est satisfaite ; et le terminal mobile reçoit un code de déverrouillage envoyé par le serveur de réseau, le code de déverrouillage étant obtenu après que le serveur de réseau a chiffré le code caractéristique à l'aide d'un mécanisme de chiffrement préréglé. Au moyen de la présente invention, le terminal mobile peut être déverrouillé automatiquement et d'une manière sécurisée.
