Abstract
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.
