Abstract
(EN)
A short Personal Identification Number (PIN) is used to transfer a subscription for wireless service to a new wireless terminal (104), thereby providing enhanced personal mobility to the subscriber. The transfer is rendered secure by the exchange of Diffie-Hellman Encrypted Key Exchange (DH-EKE) messages (110, 114).

L'invention porte sur un numéro d'identification personnel court (NIP) utilisé pour transférer une souscription d'un service sans fil vers un nouveau terminal (104) sans fil, ce qui permet à l'abonné d'avoir une plus grande mobilité personnelle. Le transfert est rendu sûr par l'échange de messages (110, 114) DH-EKE (échange de clé cryptée Diffie-Hellman).
