Abstract
A method and apparatus for personalizing a smart card coupled with a communication device of a user who is a subscriber of a first telecommunication network and wishes to become a subscriber of a second telecommunication network is disclosed. A first authentication key is stored in both the smart card and in an first application server included in the first telecommunication network. A secure session is established with a second application server included in the second telecommunication network via the first telecommunication network by negotiating with the first application server and the second application server in order that the smart card and the second application server agree on an second authentication key. Shared values and shared functions according to a secure multiparty computation protocol are used to compute a second authentication key which replaces the first authentication key in the smart card.
