METHOD OF MANAGING A SECURE ELEMENT
First Claim
1. A computer-implemented method for managing a secure element embedded in an equipment comprising an NFC controller, said secure element comprising a security indicator,wherein said method comprises the steps:
- on receipt of a triggering command sent by the NFC controller, the secure element switches in a test context in which the secure element may accept to reset the security indicator,on receipt of a restore command sent by an application, the secure element sets the security indicator to a predefined value only if the secure element is in test context,on receipt of an ending command sent by the NFC controller, the secure element switches in a Live context in which the secure element denies any attempt to reset the security indicator, said secure element keeping a track of the switch in the test context and denying any further triggering commands.

Abstract
A method for managing a secure element embedded in an equipment comprising an NFC controller. The secure element comprises a security indicator. The method comprises the steps of: on receipt of a triggering command sent by the NFC controller, the secure element switches in a test context; on receipt of a restore command sent by an application, the secure element sets the security indicator, such as a counter of unusual events, to a predefined value only if the secure element is in test context; and on receipt of an ending command sent by the NFC controller, the secure element switches in a Live context. The secure element keeps a track of the switch in the test context and denies any further triggering commands. The method enables reset of security indicator after manufacturing and test where the security indicator may have been affected.

- 6. A secure element comprising a security indicator, wherein on receipt of a triggering command received from an NFC controller, the secure element is configured to switch in a test context in which the secure element may accept to reset the security indicator, wherein on receipt of a restore command received from an application, the secure element is configured to set the security indicator to a predefined value only if the secure element is in test context, wherein on receipt of an ending command received from the NFC controller, the secure element is configured to switch in a Live context in which the secure element denies any attempt to reset said security indicator and wherein said secure element is configured to keep a track of the switch in said test context and to deny any further triggering commands.
