UICCs embedded in terminals or removable therefrom
View Patent ↗The invention proposes several improvements related to the management of secure elements, like UICCs embedding Sim applications, these secure elements being installed, fixedly or not, in terminals, like for example mobile phones. In some cases, the terminals are constituted by machines that communicate with other machines for M2M (Machine to Machine) applications.
1. Method for transmitting a subscriber identity module (Sim) application of a first terminal to a second terminal, said Sim application being stored in a secure element included in the first terminal, the access to said Sim application being locked by a Pin code, comprising:
i—exporting said Sim application from said first terminal to a distant site, by including said Pin code as well as a remote loading code;
ii—asking the user of said second terminal to enter said remote loading code in said second terminal;
iii—in the event the remote loading code entered by said user matches the remote loading code that has been exported, authorizing the installation of said Sim application in a secure element of said second terminal, and otherwise, do not install said Sim application in said secure element of said second terminal.
2. Method according to claim 1 , wherein the match of said remote loading codes is checked at the level of said distant site and said match launches the downloading of said Sim application to the secure element of said second terminal and said installation.
3. Method according to claim 1 , wherein the match of said remote loading codes is checked at the level of said second terminal, after said Sim application has been downloaded to said secure element of said second terminal, said match launching the installation of said Sim application in the secure element of said second terminal.
4. Method according to claim 1 , wherein said remote loading code is ciphered.
5. Method according to claim 1 , wherein said remote loading code is a pass phrase.
