Method for transferring securely the subscription information and user data from a first terminal to a second terminal
View Patent ↗The present invention concerns a method for transferring securely the subscription information and user data from a first terminal to a second terminal, the terminals respectively containing a first and a second UICC. According to the invention, the method consists in: i—transmitting an identifier of the second terminal to the first terminal; ii—transmitting from the first terminal to a secure vault the identifier of the second terminal and an identifier of the first UICC; iii—transmitting from the secure vault to the first terminal a subscription installation public key of the second terminal; iv—in the first UICC, packaging and encrypting the subscription information and user data with the subscription public installation key of the second terminal; v—transmitting the package to the second UICC of the second terminal; vi—installing the package on the second UICC.
1. Method for transferring securely subscription information and user data from a first terminal to a second terminal, said terminals respectively containing a first and a second UICC, said method comprising:
i—transmitting an identifier of said second terminal to said first terminal;
ii—transmitting from said first terminal to a secure vault said identifier of said second terminal and an identifier of said first UICC;
iii—transmitting from said secure vault to said first terminal a subscription installation public key of said second terminal;
iv—in said first UICC, packaging and encrypting said subscription information and user data with said subscription public installation key of said second terminal;
v—transmitting said package to said second UICC of said second terminal; and
vi—installing said package on said second UICC.
2. Method according to claim 1 , wherein steps i and v are executed over near field communication (NFC).
3. Method according to claim 1 , wherein said UICCs are embedded UICCs.
