REMOTE SMART CARD PERSONNALIZATION WITHOUT THIRD PARTY

摘要

A method and apparatus for personalizing a smart card (SC) in a communication device of a subscriber of a first telecommunication network (TN), who wishes to become a subscriber of a second TN, is disclosed. A first identity and authentication key (AK) are stored in the SC. A first application server (AS) in the first TN receives a request of subscription change comprising an identifier of the second TN, establishes a secured session with a second AS of the second TN, and sends a message comprising the first identity and AK to the second AS so the SC can access the second TN. The second AS sends a second message including a personalization command, admin code, second identity and second AK to the communication device, which executes the personalization command to replace the first identity and AK with the second identity and the second AK if the admin code is valid.

1. A method for personalizing a smart card coupled with a communication device of a user being a subscriber of a first telecommunication network and wishing to become a subscriber of a second telecommunication network, a first international identity and a first authentication key being stored in the smart card, the method comprising the following steps in a first application server included in the first telecommunication network:
receiving a request of subscription change comprising an identifier of the second telecommunication network, establishing a secured session with a second application server of the second telecommunication network identified by the identifier, sending a first message comprising the first international identity and the first authentication key to said second application server that allows the smart card to use resources of the second telecommunication network being authenticated by means of the first international identity and the first authentication key, in order that said second application server sends a second message comprising a personalization command, an admin code, a second international identity and a second authentication key to the communication device, the smart card being able to interpret the personalization command to delete the first international identity and the first authentication key and replace them by the second international identity and the second authentication key if the admin code is valid.
