Method of managing profiles in a secure element

1. A method of managing profiles in a secure element, wherein the secure element comprises a first profile associated with a first communication network, and a second profile associated with a second communication network, wherein the first profile is active, and the method comprises:

deactivating said first profile; and

activating said second profile;

wherein the deactivation and the activation occur upon detection of a failure during a local verification pertaining to said first profile for the use of said first profile, said local verification being performed in the secure element, and said failure being relative to a security failure of the first profile or to an operating failure of the first profile.

2. The method of managing profiles as claimed in claim 1 , wherein the local verification comprises verification in said secure element of the authorization for access of a user to said first profile, wherein a security failure is detected in the secure element, in the event of the failure of verification.

3. The method of managing profiles as claimed in claim 2 , wherein the verification in the secure element of the authorization for the access of a user comprises the verification of a personal identification number associated with said first profile.

4. The method of managing profiles as claimed in claim 3 , wherein the verification in the secure element of the authorization for the access of a user comprises the verification of a personal unblocking key associated with said first profile.

5. The method of managing profiles as claimed in claim 3 , wherein the verification in the secure element of the authorization for the access of a user comprises the verification of authentication data for said user.

6. The method of managing profiles as claimed in claim 3 , wherein local verification comprises verification of the integrity of said first profile, in order to detect the corrupted operation of the latter.

7. The method of managing profiles as claimed in claim 2 , wherein the verification in the secure element of the authorization for the access of a user comprises the verification of a personal unblocking key associated with said first profile.

8. The method of managing profiles as claimed in claim 7 , wherein the verification in the secure element of the authorization for the access of a user comprises a verification of authentication data for said user.

9. The method of managing profiles as claimed in claim 2 , wherein the verification in the secure element of the authorization for the access of a user comprises the verification of authentication data for said user.

10. The method of managing profiles as claimed in claim 2 , wherein local verification comprises a verification of the integrity of said first profile, in order to detect the corrupted operation of the latter.

11. The method of managing profiles as claimed in claim 1 , wherein the local verification comprises a verification of the integrity of said first profile, in order to detect the corrupted operation of the latter.

12. The method of managing profiles as claimed in claim 11 , wherein the verification of the integrity of said first profile is executed during an activation phase of said first profile.

13. The method of managing profiles as claimed in claim 1 , further comprising a reactivation of said first profile, wherein the reactivation comprises the deactivation of said second profile and the activation of said first profile.

14. The method of managing profiles as claimed in claim 13 , wherein the reactivation of the first profile is deployed upon the reception, in said secure element, of a request for the activation of the first profile ( 210 ), wherein said activation request originates from the first communication network, associated with said first profile.

15. The method of managing profiles as claimed in claim 14 , wherein said request for the activation of said first profile is generated at the request of a user.

16. The method of managing profiles as claimed in claim 14 , wherein said request for the activation of said first profile is generated upon the expiry of a predetermined time interval, with effect from a notification of the deactivation of said first profile in the secure element.

17. A secure element comprising a first profile, associated with a first communication network, and a second profile, associated with a second communication network, wherein said first profile is active, and the secure element is configured to:

deactivate said first profile; and

activate said second profile;

wherein the secure element is configured such that the deactivation and the activation occur upon detection of a failure during a local verification pertaining to said first profile for the use of this said first profile, said local verification being performed in the secure element, and said failure being relative to a security failure of the first profile or to an operating failure of the first profile.

18. The secure element as claimed in claim 17 , wherein said secure element is a card of the embedded UICC type.

19. A host device, comprising:

a secure element that includes:

a first profile, associated with a first communication network; and

a second profile, associated with a second communication network, wherein said first profile is active, and the secure element is configured to:

deactivate said first profile, and

activate said second profile, wherein,

the secure element is configured such that the deactivation and the activation occur upon detection of a failure during a local verification pertaining to said first profile for the use of this said first profile,

said local verification is performed in the secure element, and

said failure is relative to a security failure of the first profile or to an operating failure of the first profile.

20. The host device as claimed in claim 19 , wherein said host device is a portable communication terminal.
