Method for recovering a profile of a MNO
Herein provided is a solution to recover a subscription profile of a user that has lost or broken their mobile phone, smartphone, PDA, or other type of terminal. The solution reduces the risk of a subscription clone after having broken or lost their device. In one embodiment, a method herein provides for the recovering of a subscription profile loaded in a secure element that would not otherwise be retrievable from a telecommunication terminals, like eUICCs. The method includes the steps of retrieving the profile downloaded in the first secure element, and then installing it in a second secure element. Other embodiments are disclosed.
1. A method for recovering a profile of a MNO downloaded in a first secure element integrated in a first terminal, wherein said first terminal is unavailable and/or not operational, at the level of a second secure element integrated in a second terminal, said method comprising:
Transmitting from said first terminal to a SM-DP+ a first secured message containing a personal code known by the user of said first terminal along with a unique identifier of said profile, before said first terminal has become unavailable and/or not operational, wherein said personal code and said unique identifier correspond to a backup of said profile, wherein said backup of said profile is identical to said profile;
After having tested that said first secure element is not operational anymore, sending from said MNO to said SM-DP+ a recover code known by said user and said unique identifier of said profile;
Sending from said second terminal to said SM-DP+ a second secured message containing said recover code, said personal code and a unique identifier of said second secure element;
Comparing at said SM-DP+ said first and second secured messages and if they correspond, transmitting to said second terminal said backup of said profile, installing in said second secure element said backup of said profile and, upon installation success, notifying said MNO that said backup of said profile has been installed in said second secure element.
2. Method according to claim 1 , wherein said first and second secured messages are secured through hash.
3. Method according to claim 1 , wherein said first and second secured messages are secured through AES encryption.
4. The system of claim 3 , wherein said first secure element secures said first secured message with a hash and said second secure element secures said second secured messages with a hash.
5. The system of claim 4 , wherein said first and second secured messages are secured through AES encryption.
6. A system for recovering a profile of a MNO, comprisinga SM-DP+;
a MNO;
a first terminal having a first secure element therein integrated with a profile of a MNO thereon, wherein said first terminal is at least one of a mobile phone, a smartphone and a PDA, wherein said first terminal is unavailable and/or not operational; and
a second terminal having a second secure element therein integrated;
wherein, said first terminal:
transmits to said SM-DP+ a first secured message containing a personal code known by the user of said first terminal along with a unique identifier of said profile, before said first terminal has become unavailable and/or not operational, wherein said personal code and said unique identifier correspond to a backup of said profile, wherein said backup of said profile is identical to said profile,
wherein said MNO;
tests that said first secure element is not operational anymore, and, if so, sends to said SM-DP+ a recover code of said user and said unique identifier of said profile,
wherein, said second terminal;
sends to said SM-DP+ a second secured message containing said recover code, said personal code and a unique identifier of said second secure element, and wherein said SM-DP+;
compares said first and second secured messages and if they correspond, transmits to said second terminal said backup of said profile, installs in said second secure element said backup of said profile, and upon installation success, notifies said MNO that said backup of said profile has been installed in said second secure element.
