A method of replacing an authentication parameter for authenticating a security element co-operating with a terminal includes storing in the security element a first authentication parameter; transmitting to a mobile network operator the first authentication parameter for the operator to record it in its authentication system; on occurrence of an event, having a remote platform transmit to the security element an indicator informing the security element that it is authorized to replace the first authentication parameter with a second authentication parameter if its authentication fails; on occurrence of the event, having the entity transmit to the operator a second authentication parameter to replace the first authentication parameter; and in the event of subsequent failure of the security element to connect to the mobile network and if the indicator is present at the security element, replacing the first authentication parameter with the second authentication parameter at the security element.

Method of replacing at least one authentication parameter for authenticating a security element and corresponding security element

The invention concerns notably a method for detecting dynamically that secure elements are eligible to at least one OTA campaign for updating these secure elements, each secure element cooperating with a telecommunication terminal in a telecommunication network, this updating being realized by an OTA server. According to the invention, the method consists in: Detecting which secure elements have not polled the OTA server for a given time frame; Checking eligibility for these secure elements; Updating the secure elements that did not poll the OTA server for this given time frame and that are eligible to the OTA campaign by pushing messages to these secure elements.
